Dear Readers,
I welcome the readers to another edition of the DFCCIL Journal.
DFCCIL is rapidly moving along the envisioned path of attaining excellence in achieving our goals. Our sustained efforts have started showing results in shape of new railway landscape at many places . The ribbons of well laid dual tracks, the OHE structure, signalling set up & our aesthetically planned and utilitarian station buildings have all been constructed to superior quality standards with state of art technology. DFCCIL intends to provide international quality Railway Freight Transportation infrastructure to the nation. The team at DFCCIL is keenly looking forward to dedicating this mammoth and vital infrastructure to serve the country.

In this process, instruments such as ‘Total Station’
(Evolved from Theodolite) are widely used. In India,
this is the dominant form of surveying. In principle,
total station works in point by point based data
collection and very labour intensive. Taking an
example of a typical road, a section of 100 Km will
take up to 2 months of surveying and this will end in
giving discrete points at an interval of 50 m. Hence,
the resultant topographical model is not continuous
and points in between are interpolated. As the
survey includes high manual intervention, the
resultant data is error prone and oversight is required
for every work.
DRONE BASED PHOTOGRAMMETRYFOR TOPOGRAPHIC SURVEY
Dr. Y. Pari,Head, GeoSpatial Technologies,
L&T Construction
SYNOPSIS:
Geospatial technologies include all technologies that are
used to acquire, manipulate, store, analyze and present
geographic information. In construction business, all
construction activities are being constructed on or under a
geographical location. All engineering and construction
professionals need reliable geographic data for planning,
design, execution, as-built, operation and maintenance
purposes. Acquisition of such geospatial data requires
proper technology and effective methodology. Recent
developments have seen Unmanned Aerial Vehicles
(UAVs) or drones as one of the go-to tool for geospatial
data acquisition platform as it captures photos with 3X
times faster than conventional survey methods.
Combining with photogrammetry techniques, all 2D and
3D features of the project site can be collected and
measured accurately. With the usage of well-established
ground control points, accuracy can be improved
proportionally in centimetre level.
This article aims to prove how drones can effectively be
used for topographic survey in engineering and
construction industry and thereby making it one among a
promising tool for geospatial data acquisition.
Keywords: Drone, Photogrammetry, Topographic survey, GeoSpatial, GIS
ll project design requires a topographic
survey in order to know the characteristics Aof the terrain to properly design the project.
Many sensitive decisions, proposed alignment, earth
works, environmental preservation, building green
certifications etc., highly depends on the
topographical data. Topographic Survey includes
collection of data about the natural and man-made
features of the land, as well as its elevations. It is 'a
routine process for surveyors, engineers, and
construction professionals.

Geospatial technologies offer multiple 3D Scanning
solutions which scans the geography of the project
site with the different platforms. Recent
technological advancement has seen the
development of Unmanned Aerial Vehicles (UAVs)
or Drones as one of the geospatial platform from
which aerial photos over large scales at high spatial
and temporal resolution is captured. These photos
are used to generate digital terrain models and
orthophotos from which topo features can be
extracted. Hence, drones are fast becoming the end
user’s go-to tool for aerial data capture.
The extent of data collected from drone is proving to
be a game changer with respect to speed of data
delivery, cost of data capture and the products that
can be created or derived from the captured data.
Data, possibly for the first time, is now accessible to
the industry at a more frequent and cost effective
manner than ever before. Further topographic
features can be accurately identified, located and
measured from drone results. In this present article,
application of drone based topographic survey is
examined with a case study executed at CTP 3R
project site.
2. PROJECT AREA
CTP 3R is a prestigious project for L&T’s
Transportation and Infrastructure IC. The project
scope includes laying railway track for 343 running
Km. This created needs to have deep understanding
about the existing topo features and terrain
elevation. Contour maps and spot levels are essential
data for engineering design purposes. For effective
understanding, unmanned aerial vehicle platform
was chosen for 10 km of project stretch.
3. METHODOLOGY
a. Equipment Used for Topographic Survey
• DJI Phantom 4 Pro UAV was used to capture
aerial images of the project site. It carries a
camera with a 1’’ CMOS 20M Megapixel
sensor and a modified camera lens with a
focal distance of 30 mm.
• To determine positions of ground control
points 3 DGNSS Units of Trimble R8 (Static &
RTK) was used.
• For transferring the level from GTS Bench
Mark, Sokkia C32 Auto level was used.

b. Survey Work flow
The entire workflow of drone based photogrammetry is broadly classified as follows:
• Establishment of Ground Control Points (GCP)
• Mission Planning and Drone Flying
• Photogrammetry Processing
Figure 4 Placing Target sheet at site for DGNSS survey
Establishment of Control Network Survey
The control network survey acts as the backbone of any type of geospatial survey activity. It includes the establishment of both horizontal and vertical control. The horizontal control surveys coordinate horizontal position while vertical control surveys determine elevation with respect to mean sea level for which leveling instruments and SOI benchmarks are used. For the successful registration and alignment of photos collected from any UAV platform, an accurate and precisely located network of Ground Control Points (GCPs) must be acquired. Ground Control Points are points of known coordinates in the area of interest. Its coordinates are measured with Differential Global Navigation Satellite System (DGNSS) with high accuracy. It increases significantly the absolute accuracy of the project. GCPs are also used as Check points to verify the accuracy of the results. Ground Control Points will place the model at the correct location, scale and orient it. Usage of GCPs aid for measurements, overlay analysis, and comparison with previous results. The GCPs were established in well distributed manner and placed homogeneously around the project area.
The following points were followed while
establishing control network survey:
• Master pillar was established with minimum
observation of 36 hours and the data was
corrected with the nearest AUSPOS / IGS
(International GNSS Service) station.
• Primary points are established for every 5 KM
using DGNSS and the observation in static
mode with leap and frog method with minimum
of 1-hour parallel observation.
• GCP was planned at every 250m interval and its
coordinates were captured using DGNSS based

In order to get high accuracy results, a high overlap
between the images is required. Therefore, the image
acquisition plan was carefully designed in such a
way to have high overlap between each image. A
minimum of 75% frontal overlap (with respect to the
flight direction) and 60% side overlap (between
flying tracks) was maintained. Images were
captured from 60 to 75m above ground level in a
regular grid pattern. The camera was maintained at a
constant height over the terrain / object to ensure the
desired GSD. PIX4D Capture field software was
used for image acquisition. The software allows
planning and flying the missions online or offline, to
define the altitude in function of the required GSD,
camera angle, and overlap and flight speed. At the
time of acquisition, the pilot monitors the mission
using the map view and camera view. Mapview
provides the live telemetry including information
like flight altitude and flight speed while Camera
view provides the live feed from the camera. The
pilot avoids re-flying by reviewing the mission at site
itself by checking all the images directly in the app. A
bad image acquisition plan will lead to inaccurate
results or processing failure and will require
acquiring images again.
RTK mode and base point was connected with
the closest point of primary points/pillars.
• All the control network stations were processed
using appropriate GNSS post processing
software
Mission Planning & Drone Flying
The primary step in any successful drone survey is
proper mission planning. There are a few key
considerations in flight planning such as flight
altitude, wind speed, estimated flight time, ground
sampling distance (GSD), survey area, number of
photos that will be captured, and number of batteries
required for drone flying.

Before proceeding to drone survey the below
ment ioned points were cons idered for
uninterrupted survey progress.
Drone Flying information to local authorities.
Required approvals based on the flying height
from respective government departments.
Proper route planning and local support/logistics.
Avoiding the sensitive zones/forests/hills in
route planning.
Control and monitoring of survey activities.
Drone Based Photogrammetry Processing
The captured aerial images from the drone are
transferred into UAV processing software. Drone
based photogrammetry processing is based on
automatically finding thousands of common points
between images. Each characteristic point found in
an image is called a keypoint. When 2 keypoints on 2
different images are found to be the same, they are
matched keypoints. Each group of correctly
matched keypoints will generate one 3D point.
When there is high overlap between 2 images, the
common area captured is larger and more keypoints
can be matched together. The more keypoints there
are, the more accurately 3D points can be computed.
Therefore, the thumb rule is to maintain high
overlap between the images. After aligning the
drone photos, the project data was georeferenced
which comprises of fixing the ground control points
in photographs. This step is vital and plays a crucial
role in accuracy. GCPs enables to place the model at
the exact position on the Earth. Using traditional
photogrammetric principles, stereo models were
generated for the overlap region which aided to
create break lines and mass points in areas of high
undulation. Leica Photogrammetry Suite (LPS)
software was used to create the stereo models and

generating the mass point and breaklines. Mass points are irregularly spaced points, each with x/y location
coordinates and z- values used to form Triangular Irregular Networks (TIN). Breaklines define and control
surface behaviour in terms of smoothness and continuity. As the name implies, breaklines are linear features.
They have a significant effect in terms of describing surface behaviour when incorporated in a surface model.

4. RESULTS & DISCUSSION:
Results of the drone based photogrammetry survey
data was validated with the total station based
physical survey at random sample locations. By
referring the same bench marks established for
drone survey, total station based topographic
survey was carried out randomly for the same 10 km
project stretch and was compared with drone
results. Comparison of total station based co-
ordinate Vs Photogrammetry based co-ordinate at
more than 50 sample locations revealed, at most of
the locations values of x, y, z coordinates are
harmonised with conventional survey data.
However, at few locations maximum of 10 cm
difference were observed and this variation in
accuracy may be attributed to a number of factors
such as ground sample distance (GSD), flying height
of the drone, accuracy of geo-referencing etc.,
Subsequent to the validation of the photogrammetry
survey below list of deliverables are prepared.
Contours
As the drone flew at a very low altitude above
ground level, this flying height combined with high
megapixel camera resulted in a ground resolution of
3 – 4 cm per pixel. Therefore, highly precise contours
at less than 0.5 m interval were generated for the
project site (Fig 7). Contours at highly undulating
terrain are generated with better accuracy.

5. CONCLUSION
The s igni f icant benef i t of drone based
photogrammetry survey is its high dense
continuous point cloud data while total station data
is discrete and highly interpolated. With this
continuous data, earth work quantities can be
precisely estimated. Since the geography of the

the user to measure the dimension of some of
existing structures. Periodic execution of the drone

Unmanned Aerial Vehicle or Drones simply
represent a new type of remote sensing platform that
is inexpensive, easy to use, and provides users with
many new options regarding where, when, and how
geospatial imagery and data is collected. As the
technology proliferates, it is revolutionizing both
spatial data collection and geospatial analysis. This
paradigm shift brings new perspectives to a wide
range of application fields, and calls for new skills,
best practices, regulations, policies, ethics, and more.
Further, Geographic information system (GIS) relies
upon access to content, and unmanned aerial
vehicles are the game changer bringing that content
to GIS. The presence of drones in construction means
significant changes within the industry. Drones
eliminate much of the human error involved in the
process and have the ability to capture necessary
data in much less time than traditional methods.
Further, drones are also used for quantity
estimations, quality inspections, progress
monitoring etc. at various phases of a project.

LAND ACQUISITION - A VITAL LINK FOR THE SUCCESS OF AN INFRASTRUCTURE PROJECT
1.0 Introduction:
The government acquires private land for public
infrastructure project using the legal powers of
eminent domain. Acquisition of land by government
has lately drawn resistance in many cases due to
inadequate compensation for the land and loss of
livelihoods of the affected people, as well as for
involuntary displacement without proper
rehabilitation. Thus, there is a trust deficit between
the government (acquiring body) and land owners,
therefore land owners seek assistance of legal
counsellors for opposition of acquisition of their
land. According to Government of India, 435
infrastructure and highway projects are stuck across
the country and pending for completion mainly due
to delays in land acquisition. Hence, it is utmost
important that all the legal procedures laid down in
the Act for compulsory acquisition of private land
are strictly followed for timely completion of land
acquisition.
DFCCIL is acquiring about 11660 Ha land spread
over a length of 3360 Kms in eight states on two
corridors presently under construction i.e. Western
DFC & Eastern DFC. Land is a State subject but land
acquisition is a Concurrent subject. Earlier land
acquisition for all Railway projects was being done
under The Land Acquisition Act 1894 by the
respective State Governments. As railway project
normally covers more than one state, sometimes
there were delays in land acquisition as different

SYNOPSIS:Land acquisition is the basic asset needed for any infrastructure project. The doctrine of eminent domain empowers government to acquire private land for public purpose following laid down procedure in Land Acquisition Act without the willing consent of its owner. Land acquisition in India has social, economic, environmental, political and legal connotation. It involves number of sequential activities and the entire land acquisition process takes considerable time. Any mistake/error committed at any stage of land acquisition process may make it legally void and will delay completion of land acquisition resulting in project time & cost overrun. Timely completion of land acquisition is more significant for linear infrastructure projects like Railways/Highways and is critical for their successful and scheduled completion. This paper presents some precautions to be taken in different land acquisition stages for timely completion of land acquisition.

states have different set of norms and rules for land
acquisition. In order to expedite land acquisition for
Dedicated Freight Corridor (DFC) project, it was
decided to acquire land for the project under The
Railway (Amendment) Act 2008 by notifying it as
special Railway project.
2.0 Precautions to be taken in land acquisition process:
Land acquisition for Dedicated Freight Corridor,
which is a linear railway project is an important &
very critical activity. The role of competent authority
& land acquisition officers and officials of state
revenue department as well as DFCCIL is very
important for timely & successful completion of land
acquisition for DFC project. It is very important to
take due precautions to comply with legal provisions
at every stage of land acquisition process so as to
avoid any litigations. Some important precautions to
be taken during land acquisition process are
elaborated below:-
2.1 Activities prior to 20A gazette notification:
Following care should be exercised in the activities
that have to be completed before commencement of
actual land acquisition process:
• The land acquisition for a railway project under
Chapter IVA of The Railways Act, 1989 can be
carried out only if it is declared as “Special
Railway Projects” by the Central Government
through Gazette notification under clause 37 (A)
of Section 2 of the Act. Since, Western DFC and
Eastern DFC projects have been notified as
Special Railway Projects, land required
specifically for EDFC & WDFC can only be
acquired under Chapter IVA of The Railways
Act, 1989.
There are instances where Zonal Railways have
requested DFCCIL to acquire land for their
projects, which are not related to DFC project.
Any acquisition of land by DFCCIL that is not
related to DFC project under Chapter IVA of The
Railways Act, 1989 is legally not tenable.
• Central Government has been empowered to
acquire land for special railway project under
Chapter IVA of The Railways Act, 1989. As per
the Government of India (Allocation of business)
Rules 1961, the President has allocated conduct
of business of the government of India related to
Railways to Ministry of Railways. Therefore if an
executive officer of Railway Board exercises the
power of Central Government for land
acquisition under Chapter IVA of The Railways
Act 1989, he should be delegated such powers by
Minister of Railways through gazette
notification.
• ''Competent Authority'' who is authorized to
perform the functions of the competent
authority under the Act should be notified in
gazette by Central government. Such gazette
should also give official address of the
competent authority along with area for which
he is authorized to acquire land. Any change in
the competent authority or official address of
nominated competent authority should be
notified in gazette.
2.2 20A gazette notification:
20A notification is the first, but the most important,
stage of land acquisition. It is foundation of entire
land acquisition process and the successful
completion of land acquisition depends upon the
degree of accuracy of 20A notification. Following
precautions should be taken in preparation of 20A
notification:
• Latest village revenue plans should be obtained
from authorized revenue official and the plan
should be authenticated by seal and signature of
revenue officer. Land acquisition proceeding
initiated on wrong / old village revenue map
will eventually render the whole exercise futile.
• If photocopy of revenue map is supplied by the
revenue authority it should be ensured that it is
photocopied on true scale (100%) without
reduction / enlargement, otherwise it will give
wrong areas of survey nos.
• Revenue maps in different districts and states are
sometimes in different scales. Alignment plan
along with right of way should be super imposed
on revenue maps after bringing both to same
scale. To ensure superimposition of alignment
plan on village revenue map in correct
orientation, permanent physical features like
road, railway line, rivulet etc. on alignment plan,
captured during topography survey, should be
matched with corresponding permanent
features in village revenue map. Assistance of
Google map (kmz file of superimposed
alignment plan on Google map) may also be
taken for proper orientation.
JUNE 2019DFCCIL JOURNALTh
e

Similarly, revenue maps of two adjoining
villages should be properly aligned/oriented
using permanent ground features on the
boundary of two villages, which are shown on
the revenue maps.
Superimposition of alignment plan on true
alignment & orientation on village revenue map
will ensure correct identification of survey nos.
and their approximate areas to be acquired.
• The details of survey nos. and their approximate
area to be acquired should be ascertained from
land plan and revenue form (i.e. no. 7/12
followed in Gujarat).
• If the survey nos. are illegible due to revenue
map being crumpled or torn, it is better to find
out correct survey no. from field enquiry or from
grass root level local revenue officer (Patwari,
Talati etc.) rather than deducing/guessing it
from illegible revenue map.
• Since the area of a survey no. in 20 E notification
cannot exceed the area notified in 20 A
notification, in case of uncertainty in area
assessment of any survey no., it is advisable to
err on higher side.
• As mentioned in clause 20A (1) Chapter IVA of
The Railways Act, 1989, the authority exercising
powers of Central Government should record
his/her satisfaction that the land which is
intended to be acquired is required for execution
of special railway project for a public purpose.
• The doctrine of eminent domain empowers
government to acquire private land for public
purpose, provided the public nature of usage
can be demonstrated beyond doubt. Since,
clause 20 A (2) of the Act requires to give a brief
description the special railway project for which
the land is intended to be acquired, hence apart
from giving brief description of special railway
project, the public purpose which it will serve
should be given in detail in 20A notification.
This will help in defending any court case when
the court weighs balance of convenience
between public purpose and private interest.
• Since government land is not acquired but
transferred, competent authorities in some
states do not include government land in 20A
notification. If government land required for the
special railway project is not notified in 20 A
gazette, a person having interest on the
government land such as easement right or
livelihood will be deprived of his right to object
to acquisition of the land. In order to give such
person/s opportunity to object to transfer
(acquisition) of government land under clause
20 D (1) of the Act, it is advisable that details of
government land required for the project should
also be included in the 20A gazette notification.
• As soon as 20A gazette notification is issued,
state revenue officials should be impressed
upon to enter the effect of 20 A gazette
notification in revenue records (form no. 7/12)
of survey numbers intended to be acquired. This
will create “other right” (Bija Hakka) in the
revenue records of survey nos. to be acquired for
the project and land owner will not be able to
change the ownership of the land.
2.3 Clause 20D:
• There should not be abnormal delay in
publication of 20A gazette notification in two
local newspapers one of which shall be in a
vernacular language.
• Minimum period of 30 days from publication of
20A gazette notification in the newspapers
should be given to the PAPs to submit objections
to acquisition of their land.
• Most of the objections of Project Affected
Persons (PAPs) against 20A gazette notification
are against alignment and/or project itself.
Competent authority, being a non-technical
person, sends the objections to acquiring body
for remarks. Detailed factual remarks should be
given on each objections of PAPs, because
competent authority may decide the objections
based on the remarks given by the acquiring
body.
However, it should be ensured that competent
authority does not simply give reference of or
forward the remarks of acquiring body in his
order on objections of PAP. Such action will be
construed as competent authority acting as
subservient of acquiring body and/or incapable
to decide the objections.
• Reasonable opportunity of being heard, either in
person or by a legal practitioner, should be given
to all the PAPs who have objected to the
acquisition of their land.
JUNE 2019DFCCIL JOURNALTh

• Competent authority should give detailed
reasons (speaking order) for disallowing/
allowing each objections of the PAP and the
order should be communicated to the PAP in
writing.
• The decision regarding allowing/disallowing of
the objections should be communicated to PAPs
individually rather than giving a common reply
to large number of PAPs, although they may
have submitted similar objections (the court may
treat it as mechanical exercise by the competent
authority without application of mind).
Competent authority should give his own
reasoned order on the objections based on
remarks of the acquiring body.
• Reasonable opportunity should be given to
PAPs for submission of objections against
acquisition of their land, hearing of their
objections and communication of decision on
their objections; because in many cases court
have viewed that only opportunity available to
PAPs to object to compulsory acquisition of their
land is under clause 20D of the Act. Any
shortcut/mistake committed in following
procedure laid down in clause 20D of the Act
will make the entire land acquisition proceeding
vulnerable to judicial intervention.
2.4 Joint Measurement Survey (JMS):
Joint Measurement Survey is carried out to ascertain
exact area of land to be acquired, details of trees, and
other structures thereon the land. Joint Measurement
Survey becomes basis for area of land to be acquired
for declaration under Section 20 E and subsequent
preparation of award.
• Advance notice should be issued by Competent
Authority giving schedule of Joint Measurement
Survey in each village. This notice should be
displayed in prominent places of the concerned
village so as give wide publicity. Records of such
JMS notices should be maintained.
• Before taking up JMS, the land (right of way) to
be acquired should be properly demarcated on
site by fixing pillars on the ground. This will
increase the accuracy of JMS.
• Efforts should be made to associate PAPs in the JMS
so that details of all immovable assets on the land
like structures, buried pipelines, bore-wells, trees
(along with type) etc. can be recorded in the JMS.
Survey sheet should be jointly signed by revenue
official, official of acquiring body & owner of land.
This will reduce post award disputes by PAPs.
• All the immovable properties including trees
(nos. if there are large nos. of trees in the survey
no.) should be shown on the JMS sheet.
2.5 20E gazette notification:
• Before finalization of acquisition proposal, land
plans should be verified with records of grass
root level revenue officials (i.e. Patwari, Talati
etc.) to know latest survey number which may
have got changed due to division of land in a
particular survey number. The ownership of
survey numbers should be checked with latest
revenue records (form no. 7/12).
• Most of the correspondence of competent
authority on land acquisition matters is with
Chief Project Manager (CPM) of DFCCIL, who
is authorized by Ministry of Railways to acquire
land on behalf of Railways. However, it should
be ensured that report specified in clause 20 E (1)
of the Act should be addressed/submitted to
Central Government by competent authority
and not to CPM/DFCCIL.
• It should be ensured that area of survey number
in 20E notification should not be more that the
area of survey number published in 20A gazette
notification.
2.6 20F gazette notification:
• Valuation of structures, trees and any other
immovable property on the land proposed to be
acquired must be got done through Govt.
approved valuer; for valuation, preference
should be given to government departments
(R&B/PWD) for structures and forest/
horticulture department for non-fruit bearing/
fruit bearing trees.
• The land compensation award comprises of (i)
Compensation of land based on market value and
(ii) compensation of assets based on replacement
cost. However, it should not be split.
• The amount of land award should be deposited
in the bank account of competent authority
immediately after declaration of the award or
before declaration of award if asked by the
competent authority.
• There is no provision of interest on land award
compensation for period from initial
JUNE 2019DFCCIL JOURNALTh
e
17
notification to date of disbursement of award in
the earlier Railway Amendment Act 2008 and
for the period after declaration of land award to
date of disbursement of award in RFCTLA Act
2013. Hence, efforts should be made to disburse
land award compensation to PAPs as soon as
possible/immediately after the declaration of
land award to avoid any legal issues. In a case,
the court has awarded interest on delayed
payment of land award.
• There are two parts of compensation in land
acquisition (i) cash compensation of land
including immovable assets thereon (20F) and
(ii) Rehabilitation & Resettlement (R&R)
benefits. Efforts should be made to disburse the
two compensation simultaneously.
• Mutation: the process of mutation of acquired
land to change of ownership in the name of
Indian Railways should be started immediately
after disbursement of land award. The
ownership of Indian Railway on acquired land
should also be reflected in other revenue
records/forms.
3.0 Government land and forest land:
• Government land: The process of transfer of
government land takes considerable time
because it also involves obtaining no objection
certificate (NOC) from various government
departments like R&B/PWD, Irrigation, Inland
waterways authority of India (IWAI), Gram
Panchayat etc. Hence, the process of transfer
(ROW)/right of use (ROU) of government land
should also be initiated & completed along with
compulsory acquisition of private land.
• Forest land: The forest department under MoEF
g i v e s p e r m i s s i o n f o r d i v e r s i o n o f
social/reserved forest land and land of wild life
sanctuary and the entire process of obtaining
diversion permission from forest department
(MoEF) takes significantly long time. Hence, it is
important to identify forest/wild life sanctuary
land falling on DFC alignment early in
consultation with forest department and
immediately initiate action for diversion of such
land as per the prevalent Acts.
4.0 Conclusion:
Successful completion of any infrastructure project
depends upon timely acquisition of land. Large
number of infrastructure projects in the country are
held up mainly due to delay in land acquisition. The
land for public infrastructure projects is acquired
through laid down procedures in land acquisition
Acts. Since, there is a trust deficit between acquiring
body and land owners due to inadequate
compensation hence, PAPs strongly oppose
acquisition of their land and always look for any
lapse/mistake in land acquisition process for
challenging it in court, which may delay the land
acquisition. The suggested precautions, if followed,
will help in smooth and faster acquisition of land for
infrastructure projects particularly for future special
railway projects.
“DFCCIL has just started its journey with present
two under construction corridors (EDFC & WDFC)
and it has to go a long way. The experience gained by
it in land acquisition, if applied in future corridors,
will surely ease DFCCIL’s long journey on the path
of railway infrastructure development in India”.

Use of TILOS in EDFC-2
1. Introduction:
Traditional project management tools display
schedules in Gantt chart or network diagrams.
Creating linear project plans using traditional
SYNOPSIS:TILOS (TIme LOcation Software) is being used in Eastern Dedicated Freight Corridor (EDFC-2 project by PMC (Systra Mott JV) primarily for reporting purposes. The use of TILOS in the project enables a distance (location) based view of the project. Progress of activities is also recorded and analyzed linearly. Use of TILOS in scheduling helps in optimized crew movement. This in turn prevents over/under utilization of resources.This paper focuses on the features of Linear Scheduling, its benefits over traditional Gantt chart schedules and ways in which TILOS can be a useful tool in project scheduling and controlling.

Gantt software can be cumbersome and
inaccurate. Linear projects are the projects
which have a definite ROW and repetition of
activities.

2. Advantages of using Linear Project
Management Software:
TILOS has its advantages over traditional methods,
which are:
• Linear Scheduling provides more information
than traditional CPM and bar chart scheduling,
it provides a clear picture of when and where
activities take place.
• Eliminates planning mistakes.
• Graphically displays the work plan allowing a
feel for the distribution of resources and crew
movement
• Easily illustrates working limitations such as:
stream crossings, utility crossings, topography,
ROW acquisition, and lane closures
• Provides maximum flexibility in organizing
your plan.
• Much faster creating and updating project plan.
• Easy to understand by all project team.

Exhibit 2: Basic of Linear Scheduling
3. Creating Linear Schedule quickly:
TILOS can be used as a standalone planning system or
in combination with other planning systems. Either
way, TILOS allows quick creating of a linear schedule.
• Draw your plan: The time distance diagram in
TILOS allows you to draw the activities on the
time-distance view like drawing on a piece of
paper. The templates for the tasks are pre-defined
and can be of a shape, style and colour of your
liking.
• Import your plan: If the tasks are too many, a
simply copy-paste can be used to create the plan
and other attributes such as relationships,
resource allocations, distance diagram, symbols
etc.
• Easily duplicate repetitive work: Repetitive
work sequence can be copied and pasted on
different locations. The new location is identified
automatically.
4. Describe project site details:
Project site details are can be recreated with the
schedule. Having risk elements, utilities, lane
closures, land hindrances and other features, which
can affect the work progress, with the schedule
allows you to be proactive and avoid and planning
mistakes.
• S y m b o l s a n d p i c t u r e : S y m b o l s f o r
representation of site utilities can be produced in
TILOS and used with the schedule. Actual
photographs from the site can also be used for
better understanding of project site features. For
EDFC-2, symbols for bridges have been
incorporated in the accordance to the progress of
works. Green for completed, yellow for in
progress and red for not started.
• Distance Graphs: Graphs can be prepared on the
distance axis having land profile data. The
topography of the project can be created and
viewed with the schedule.

• Speed Profiles: Non-linear work rates/ productivity of the activities pertaining to the different sections
of the project such as an extremely rocky area shall take more time than a sandy area. Same way profiles
for different seasons can also be created. The duration of rainy seasons may have a lower work rate as
compared to winter season.
• Additional Information: Any additional information pertaining to site or the project can also be
incorporated easily with the schedule.

6. Features:
Some of the noteworthy features in TILOS are:
• Fully customizable Gantt chart: TILOS automatically creates a Gantt chart in accordance to the attributes
in Time distance view. A location based Gantt chart can also be generated. Charts can be grouped on the
basis of activities, resources or normal progression of tasks.
• Overlapping of tasks can be detected: TILOS has feature named as “Clash Detection” which allows the
user to detect overlapping mistakes. This is primarily due to a planning/scheduling mistake. Hence, it
helps eliminate any planning mistakes.
Exhibit 8: Gantt chart view
Exhibit 9: Overlapping tasks detected in TILOS
• One page output: Schedule, plan & profile, cash flow, resources, site features etc. are visible in a single
page output. A 40 page schedule on Primavera can be represented in a single page on TILOS.

7. Conclusion:
Use of a linear project management tool as the
primary scheduling tool or with any other tool can be
very helpful in analysing the location (distance) and
time (schedule) together. “Time distance view” is the
answer to all the question involving crew
mobilization, optimum utilization of resources
etc., which is not possible in a traditional project
management tool like Primavera. Some of the
ways in which TILOS is a better tool than P6 in
planning, monitoring and controlling linear
projects are:
With increasing number of railway projects in India,
presence of TILOS as primary or a secondary
planning tool in every project must be mandatory
because of its capabilities enabling the scheduler to
prepare a realistic work schedule and avoid any
planning mistakes.

FREIGHT TRANSPORT IN INDIA AND DEDICATED FREIGHT CORRIDORS
A well planned and coordinated system of transport
plays an important role in building and sustaining
the economy of a country. A good transport system
enables economic growth by providing essential
connectivity between available resources, centres of
production and the market. It is also an essential
factor in promoting balanced regional growth by
ensuring the delivery of goods and services to all in
the remotest part of the country.
India has one of the most spread transport network
on the planet, but it has been plagued by very slow
and inefficient movement of passenger and freight.
The sector is faced with many constraints and
challenges. India's transport demand has grown by
almost 8 times since 1980 -more than any other Asian
economy. The penetration of the transport network
in remote areas and difficult terrains is inadequate.
Highways are narrow, congested, and ill
maintained, causing sluggish traffic, and a menace
of pollution. Frequency of accidents are high,
leading to loss of more than 1.5 lac lives every year. A
very high percentage of the freight moves on roads
even though this is the costliest mode of transport,
with the highest pollution burden. Rail transport is
cheaper and more environment friendly than road
transport but the network is slow and inadequate,
while the waterways which are the cheapest and
least polluting of the three are very unorganised and
meagrely developed. The result of such modal mix is
high logistics costs that make our goods non-
competitive in the international market.
This picture has, however, started changing in recent
times. The government has made it a major priority
to build a world class transport infrastructure in the
country that is cost effective, easily accessible to
everyone, safe, creates minimum load of pollutants
and relies on indigenous inputs to the maximum
possible extent. This has been possible with
strengthening of the available infrastructure by
leveraging world class technology, building new
infrastructure and modernizing the legislative
framework to support this work. Government has
embraced partnering with the private sector and
intends to achieve enabling environment for such
partnership.
Transport has recorded an extensive growth over the
years both in spread of network and in output of the
system. The most important means of transportation
in a country are roads, railways, airways, and
waterways. With the vast expanse of India a very
large and integrated network of various modes of
transport and logistics framework is essential.
Although India has completely revolutionized its
Sh. Biplav KumarGGM/BD
SYNOPSIS:India has a very vast land area with varieties of landscape and topographical features, and extremely long costal boundary throwing a big opportunity and challenges for domestic and international transportation.The country faces multifaceted challenges in expeditious development and integration of Rail, road, inland waterways, air and Sea-Port infrastructure to meet the freight movement requirement of the country which can serve the remotest parts of the nation and act as catalyst for the boosting of freight connectivity and economic development ultimately.This article deals with the status of various freight infrastructure in India, achievements, possibilities of progress, approach required and how Dedicated Freight Corridor will embed in the transport system and act as a game changer for Indian freight transportation.

transportation system in recent times, much is still
needed to be done to adequately meet the demands
of this nation. Transport infrastructure at a much
higher scale of capacity is imperative to enable India
stand in the league of countries like China, USA,
Australia etc.
It is desirable to take stock of strengths and
weaknesses of different modes of transport in India
to reach at the desirable roadmap for concerted and
planned development of transport and logistics
system and thereby position an efficient and cost
effective supply chain network.
Road Transport
India has a vast network of roads, both metalled and
unmetalled. However, this means of transport and
communication are still inadequate for our needs.
Before the advent of railways, roads were the only
means of communication for the exportation of
surplus produce. With the extension of the railway
system, it has become more and more necessary to
construct roads to feed the railways.
At present, the economic loss caused by the
inaccessibility of many agricultural districts in the
rainy season is very great. In sandy, hilly, and forest-
covered tracts and in other parts of the country,
where railways have not penetrated, road transport
still holds an important share of long-distance traffic.
The opening of railways has created a demand for
road-construction, which must be met by the local
and provincial bodies. The question of developing
the roads is also of vital importance. We cannot
expect any significant progress in our rural economy
unless there are good road connections between
villages and towns.
India has second largest road networks in the world,
spanning a total of 5.5 million kilometres (kms).
Production of commercial vehicles increased to
894,551 in 2017-18 from 567,000 in 2009-10 at a CAGR
of 5.87 per cent.
The private sector has emerged as a key player in the
development of road infrastructure in India.
Increased industrial activities, along with increasing
number of two and four wheelers have supported the
growth in the road transport infrastructure projects.
The government’s policy to increase private sector
participation has proved to be a boon for the
infrastructure industry with a large number of
private players entering
the business through the public-private partnership
(PPP) model.
With the Government policy supporting 100 per cent
foreign direct investment (FDI) in the road sector,
several foreign companies have formed partnerships
with Indian players to benefit from the sector's
growth. MAIF 2 became the first largest foreign
investment in Indian roads sector under Toll Operate
Transfer mode worth Rs 9,681.5 crore (US$ 1.50
billion). In May 2018, the Government of India signed
US$ 500 million loan agreement with World Bank to
provide additional funding for construction of 7,000
km climate resilient roads out of which 3,500 km will
be built using green technologies under Pradhan
Mantri Gram Sadak Yojna (PMGDY). As of
November 2018, total length of projects awarded
under Bharatmala Pariyojana (including residual
NHDP works) was 6,460 kms for a total cost of Rs 1.52
trillion (US$ 21.07 billion). The total amount of
investments* are estimated to reach Rs 1.58 trillion
(US$ 2.25 billion) in FY19.
The Ministry of Road Transport and Highways has
fixed a target for construction of 10,000 km national
highways in FY19. The Government of India aims to
complete 200,000 km national highways by 2022. In
the coming years, NHAI’s increased delegation
autonomy along with Bharatmala Pariyojana
initiative is expected to enable growth in awarding
momentum. The Bharatmala Programme will link
border and international connectivity roads, develop
economic corridors, intercorridors and feeder routes,
improve connectivity of national corridors, build
coastal and port connectivity roads, and greenfield
expressways.
The road network transports 64.5 per cent of all
goods in the country and 90 per cent of India’s total
passenger traffic uses road network to commute.
Road transportation has gradually increased over
the years with the improvement in connectivity
between cities, towns and villages in the country.
In India sales of automobiles and movement of
freight by roads is growing at a rapid rate. In January
2019, more than a million-and-half (1,607,315) new
vehicles were bought and registered with various
regional transport offices across the country. That
comes to an average of more than 51,000 new vehicles
bought across India, every single day of January.
And according to latest data from the Ministry of
JUNE 2019DFCCIL JOURNALTh
e
25
Road Transport and Highways (data till 2016), there
were 230 million registered vehicles in India as on
March 31, 2016. The total number of registered
motor vehicles grew at a compounded annual
growth rate (CAGR) of 9.9% between the 2006 and
2016 decade.
Among different category of vehicles, highest
CAGR of 10.1% each were recorded by two-
wheelers and cars, jeeps and taxis. Goods vehicles
and buses recorded CAGR of 9% and 5.9%
respectively. While, India’s road network (including
national highways etc) grew by just about a third in
the last decade, vehicle registrations have increased
by almost three times. This single statistic should
reveal why Indian roads are getting more congested
with each passing month and why policymakers
need to worry about consequences of this increased
congestion: increased vehicular pollution, increase
in the number of road accidents and a monumental
wastage of money as well as time spent commuting
daily. The construction of highways reached 9,829
km during FY18 which was constructed at an
average of 26.93 km per day. The Government of
India has set a target for construction of 10,000 km
national highway in FY19.
Total length of roads constructed under Prime
Minister’s Gram Sadak Yojana (PMGSY) was 47,447
km in 2017-18.
Key Investments/Developments:
The Union Government aims to boost corporate
investment in roads and shipping sector, along with
introducing business-friendly strategies that will
balance profitability with effective project
execution. According to data released by the
Department of Industrial Policy and Promotion
(DIPP), construction development including
Townships, housing, built-up infrastructure and
construction-development projects attracted
Foreign Direct Investment (FDI) worth US$ 24.87
billion between April 2000 and June 2018.
Some of the key investments and developments in
the Indian roads sector are as follows:
• A total of 892 km and 2,345 km national highway
projects were awarded and constructed,
respectively between April –August 2018.
• The first phase of construction work of Mumbai's
29.2 km long coastal road began in 2018.
Some of the recent government initiatives are as
follows:
• As of October 2018, total length of projects
awarded was 6,400 kms under Bharatmala
Pariyojana (including residual NHDP works).
• As of August 2018, a total length of 34,800 km
road projects have been proposed to be
constructed, under Bharatmala Pariyojana
Phase-I.
• As of August 2018, Government of India has
approved highway projects worth Rs 2 billion
(US$ 29.83 million) to improve connectivity
among Gujarat, Maharashtra, Rajasthan,
Madhya Pradesh and Diu.
Achievements
Following are the achievements of the government
in the past four years:
Road Ahead
The government has taken various new steps and is
making conducive policies to attract investments at
an unprecedented level. Around 200,000 km

Apart from adding road lengths , government is also
committed to make the highways safe for travel. For
this, a multi-pronged approach has been adopted
that includes incorporating safety features in road
designs, rectifying known accident black spots,
proper road signage, more effective legislation,
improved vehicular safety standards, training of
drivers, improved trauma care and enhanced public
awareness.
Under the Setu Bharatam programme all railway
level crossings are to be replaced with over bridges
or under passes and an inventory with structural
rating of all bridges on national highways is being
created so that timely repair or rebuilding actions
can be undertaken.
Ports
According to the Ministry of Shipping, around 95 per
cent of India's trading by volume and 70 per cent by
value is done through maritime transport.
India has 12 major and 200 notified minor and
intermediate ports. Under the National Perspective
Plan for Sagarmala, six new mega ports will be
developed in the country.
The Indian ports and shipping industry plays a vital
role in sustaining growth in the country’s trade and
commerce. India is the sixteenth largest maritime
country in the world, with a coastline of about 7,517
km. However, installed handling capacity of India's
ports is much behind countries like China.
The Indian Government plays an important role in
supporting the ports sector. It has allowed Foreign
Direct Investment (FDI) of up to 100 per cent under
the automatic route for port and harbour
construction and maintenance projects.
It has also facilitated a 10-year tax holiday to
enterprises that develop, maintain and operate ports,
inland waterways and inland ports.
Market Size
During FY18, cargo traffic at major ports in the
country was reported at 679.36 million tonnes (MT).
In FY19 (up to November 2018) traffic increased by
4.83 per cent year-on-year to reach 461.22 million
tonnes. Cargo traffic at non-major ports was
estimated at 491.95 million tonnes FY18 and grew at
9.2 per cent CAGR between FY07-18.
The major ports had a capacity of 1,452 million
tonnes by FY18 end. The Maritime Agenda 2010-20
has a 2020 target of 3,130 MT of port capacity.
The government has taken several measures to
improve operat ional e f f ic iency through
mechanisation, deepening the draft and speedy
evacuations.
Investments/Developments
• Essar Ports will invest US$ 70 million in Hazira
port by 2020.
• The Indian Minister for Shipping, Road
Transport and Highways, Mr Nitin Gadkari,
announced a massive investment in India’s ports
and roads sector, which is likely to help boost the
country’s economy. The Indian government
plans to develop 10 coastal economic regions as
part of plans to revive the country’s Sagarmala
(string of ports) project.
• T h e z o n e s w o u l d b e c o n v e r t e d i n t o
manufacturing hubs, supported by port
modernisation projects, and could span 300–500
km of the coastline.
The government is also looking to develop the
inland waterway sector as an alternative to road
and rail routes to transport goods to the nation’s
ports and hopes to attract private investment in
the sector.
• Ports sector in India has received a cumulative
FDI of US$ 1.64 billion between April 2000 and
June 2018.
• Indian ports and shipping sector witnessed three
M&A deals worth US$ 29 million in 2017.
Some of the major initiatives taken by the
government to promote the ports sector in India
are as follows:
• Net profit at major ports has increased from Rs
1,150 crore (US$ 178.4 million) in FY13 to Rs 3,413
crore (US$ 529.6 million) in FY18 while operating
margin increased from 23 per cent to 44 per cent.
• In May 2018, Ministry of Shipping allowed
foreign flagged ships to carry containers for
transshipment.
• In March 2018, a revised Model Concession
Agreement (MCA) was approved to make port
projects more investor-friendly and make
investment climate in the sector more attractive.

Road Ahead
Increasing investments and cargo traffic point
towards a healthy outlook for the Indian ports
sector. Providers of services such as operation and
maintenance (O&M), pilotage and harbouring and
marine assets such as barges and dredgers are
benefiting from these investments.
The capacity addition at ports is expected to grow at
a CAGR of 5-6 per cent till 2022, thereby adding 275-
325 MT of capacity.
Under the Sagarmala Programme, the government
has envisioned a total of 189 projects for
modernisation of ports involving an investment of
Rs 1.42 trillion (US$ 22 billion) by the year 2035.
Ministry of Shipping has set a target capacity of over
3,130 MMT by 2020, which would be driven by
participation from the private sector. Non-major
ports are expected to generate over 50 per cent of this
capacity.
India’s cargo traffic handled by ports is expected to
reach 1,695 million metric tonnes by 2021-22,
according to a report of the National Transport
Development Policy Committee. Within the ports
sector, projects worth an investment of US$ 10 billion
have been identified and will be awarded over the
coming five years.
Waterways
Water transport is the oldest and cheapest form of
transport. It is one of the most important external
and internal means of transport in all the civilized
countries of the world. It is useful for the carriage of
bulky and heavy goods.
In India, we have many great river systems.
However, they are unevenly distributed, some of
them are fully utilized for irrigation purposes, and
some others are naturally unfit for navigation.
In some parts of India, however, waterways are still
extensively used for navigation purposes. Efforts are
underway to utilise the navigational potential of
India's 7500 km long coastline and over 14,000 km of
inland waterways through the Sagarmala
programme and by declaring 111 waterways as
National Waterways. Sagarmala envisages

developing port as growth engines . The idea is to
industrialise the port areas by developing 14 coastal
economic zones.
This would be supported by modernisation and
augmentation of the port infrastructure, improving
connectivity of ports with the hinterland through
road, rail and waterways, and development of the
coastal community . It is expected that besides
saving Rs 35000-Rs 40000 Crores as logistics cost
annually ,boosting exports by about USD 110 billion
and generating one Crores new jobs, Sagarmala will
also double the share of domestic waterways in the
modal mix in the next ten years.
In addition, work is on over several waterways
including Ganga and Brahmaputra to develop their
navigational potential. The world Bank aided Jal
Marg Vikas project on Ganga aims to develop the
river stretch from Haldia to Allahabad to allow
navigation of 1500-2000 tonne ships.
Work on building multi modal terminals at
Varanasi, Sahibganj and Haldia and other necessary
infrastructure on this stretch is progressing. With
this, much of the cargo movement to the eastern and
north eastern parts of the country can be done
through waterways resulting in lowering of the price
of commodities. In 2017, thirty seven more
waterways were planned to be developed in the next
three years. In India, more navigable rivers and
canals should be made. And, a systematic policy for
the development of the inland water transport
should be pursued.
Air Transport System
Proper attention must also be given at the same time
to air transport as another means of national and
international communication. India possesses some
natural advantages in this respect and they have to
be fully exploited for development of airways.
The Government is taking a keen interest in the
expansion of civil aviation not only for its
importance as a means of transport but also because
of its strategic value in the matter of national defense.
Air cargo handled in Indian airports grew by more
than 20 times from 0.08 MMT in 1972-73 to 2.5 MMT
in 2014-15. During the period 2013-14 to 2017-18 it
accelerated sharply and grew with a CAGR of 10.0 %.
Cargo traffic in India crossed 2.98 million tonnes in
FY2017. International cargo comprises of 60 % of
total air cargo tonnes handled in India and grew at
15.6 % in 2017-18.Domestic cargo grew by over 8%,
which reflects the skewed modal mix in which
roads accounts for over 60% of cargo transportation
as compared to the global average of around 30 %.
Indian express industry is one of the fastest growing
market globally, but with a small share of about 2%
of the global market. This industry grew at 17%
CAGR over the past 5 years and was estimated to be
INR 22,000 Crores in 2016-17.Domestic express
industry ,a key constituent of the Indian express
industry ,is estimated to be worth INR 17,000crore .
International express industry is estimated to
contribute INR 5,000 Crores (23% by value) to the
Indian express industry. Transshipment cargo
which constitutes about 60-70 % of total volumes
handled by some of the leading global airport is
quite low in India. However, the industry is
expected to grow at a CAGR of 17 % for the next five
years.
The Indian air cargo industry is poised for
significant growth on the back of both the strength of
India's economic growth and many other drivers of
growth in India's commerce, trade, investment and
consumption ,which include significant demand
from small and medium B2B segments.
Domestically plans are afoot to make metro airports
cargo hubs catering to the neighbouring regions.
Internationally too, India has significant potential to
be a transshipment hub for international cargo
movement from other countries. India needs a multi
fold approach to development of cargo
infrastructure which looks as upgrading existing
cargo terminals with advanced technologies,
development of new cargo terminals at airports,
dedicated cargo airports, and air freight stations.
High dwell time leads to significant transaction costs
and operating expenses for the air cargo operators.
One way to achieve lower dwell time to match with
international standards is air freight stations, which
can help to decongest airports and offer value
additions.
The magnifier impact of lower air freight costs in
India is as yet not seen adequately. High logistics
cost in India has also hampered the growth of air
cargo logistics industry. A strong boost has been
tried through the holistic National Civil Aviation
Policy 2016. This includes a number of initiatives for

achieving growth of cargo volumes to 10 Million
tonnes by 2027. Open Sky Policy for air cargo and
improved international connectivity coupled with
expanding cargo - handling infrastructure, both
physical and digital have sustained the high growth
of air cargo in India in the last few years. As per the
Boeing 20 year Forecast, while global air cargo would
reach 509 billion Revenue Tonne Kilometers (RTKs)
by 2035 i.e. twice that seen in 2015, at an annual
average rate of 4.2 %, Asia will lead the growth, with
domestic China, intra-Asia, and Indian market
expanding at the highest rates of 6.2%, 5.5% and 6.7%
per annum respectively .
It is felt that the focus on improvement in the Ease of
Doing Business in India coupled with landmark
Government of India initiatives like 'Make in India',
and 'Digital India', coupled with suitable policy
,logistics, regulatory, and skills regime will all
contribute to facilitating accelerated growth in air
cargo. Simplication, modernization and
harmonisation of export and import processes as
well as of the end -to-end domestic supply chains are
an important issue. The WTO's Trade Facilitation
Agreement (TFA) encompasses several provisions
for ensuring expedited movement, release and
clearance of goods and sets out measures for effective
cooperation between customs, related authorities on
trade facilitation and customs compliances. India has
adopted a WTO- Plus plan of action to implement the
commitments arising from the TFA. Globally, air
transport is a highly dynamic industry and in this
regard, the industry in India is no different. As
markets evolve and customer demands change, air
cargo operators must constantly review and update
their operations and product offering to ensure that
they continue to meet the market need. Accordingly,
the Ministry of Civil Aviation has now articulated its
vision for the comprehensive National Air Cargo
Policy which support the sustainable acceleration of
the air cargo industry in India and ensuring global
competitiveness with performance benchmarking
and monitoring.
An analytic study of the above facts justifies the
conclusion that the transport system of India is
making good progress. The Government is
providing all reasonable facilities for the
development of the country’s transport. It is for the
people to take advantage of the facilities offered and
to step up the country’s progress in the way we
desire.
Millions of tons of raw materials and finished goods
have to be transported over long distances and in the
absence of transport facilities there will be
bottlenecks in the transport of goods leading to
undesirable consequences.
To get the most from massive investments, India
must adopt a coordinated approach that aligns the
development of each transport mode with the
country’s needs.
Logistics infrastructure is a critical enabler of India’s
agenda for economic development and
urbanization. Despite sizeable investment in
logistics sector ,the country’s network of roads, rail,
and waterways will be insufficient to accommodate
a threefold increase in freight movement over the
coming decade. This shortfall in logistics
infrastructure will put India’s growth at risk,
concludes a new McKinsey report, Building India:
Transforming the nation’s logistics infrastructure.
Since a large part of the logistics network that India
needs has yet to be built, the country has a chance to
add infrastructure optimally to meet the growing
demand.
The report finds that to achieve this goal, India must
pursue an integrated and coordinated approach that
not only closely aligns the development of each
mode—railways, roads, and waterways—with the
country’s needs but also makes better use of existing
assets.
This will require increasing the railways’ share of
logistics infrastructure investments from about 40
percent currently to 50 percent. Building a logistics
infrastructure capable of handling rising freight
traffic more efficiently presents opportunities for
user industries and for infrastructure developers
and construction companies, among others, the
report finds.
In particular, India must expand its use of rail and
realize the potential of its waterways. Given current
trends, the share of India’s freight transported by rail
would decline to 25 percent, from the current 36
percent. By contrast, rail accounts for almost 50
percent of freight movement in China and the United
States. The report suggests an approach where India
could increase rail’s share of its freight to 46 percent
by 2020 (exhibit).

Indian Railway :In India, there are equal number of challenges and
opportunities. Rail experts believe that the rail
transport systems are six times more energy efficient
than road and four times more economical.
The social costs in terms of environment damage or
degradation are significantly lower in rail. Rail
construction costs are approximately six times lower
than road for comparable levels of traffic.
Historically, the Indian railways have played a
leading role in carrying passengers and cargo across
the country. The Indian railways is one of the largest
railway networks carrying about 23 million
passengers and hauling nearly 3.18 million tonnes of
freight daily. With the current freight system ,there
are challenges in the present IR freight handling
system leading to inadequate service reliability and
higher costs for end users.
These challenges are mostly related to inadequate
infrastructure, rolling stock, insufficient line
capacity which have contributed to the declining
trend in overall rail share.
Railways are the most important means of
transportation in India.
The improvement in railway communications in
recent times has played a most important part in the
internal development of the country. They have
brought the different parts of the country closer.
The advent of the railway has been of special
advantage to the peasantry. Social and political
influences from railway construction have been no less.
Advantages of Railways
• Travelling has become cheaper;
• Defense of the country is less difficult.
• Greater peace and order is maintained in the
country, and
• The spirit of nationalism has very greatly
developed.
• Freight mobility on rail has major contribution in
economic development of India.
The Indian Railways is among the world’s largest
rail networks. The Indian Railways track length
network is spread over 115,000 km, with 12,617
passenger trains and 7,421 freight trains each day
from 7,349 stations plying 23 million travellers and 3
million tonnes (MT) of freight daily. India's railway
network is recognised as one of the largest railway
systems in the world under single management.
The railway network is also ideal for long-distance
travel and movement of bulk commodities, apart
from being an energy efficient and economic mode
of conveyance and transport. Indian Railways has
been the preferred carrier of bulk commodities,
automobiles and for long distance haulage in general
in the country .
The Government of India has focused on investing
on railway infrastructure by making investor-
friendly policies. It has moved quickly to enable
Foreign Direct Investment (FDI) in railways to
improve infrastructure for freight and high-speed
trains. At present, several domestic and foreign
companies are also looking to invest in Indian rail
projects.
Market SizeIndian Railways’ revenues increased at a CAGR of
9.66 per cent during FY07-FY18 to US$ 27.71 billion
in FY18. Earnings from the passenger business grew
at a CAGR of 9.90 per cent during FY07-FY18 to reach
US$ 7.55 billion in 2017-18P. Freight revenue rose at a
CAGR of 9.83 per cent during FY07-FY18 to reach
US$ 18.16 billion in 2017-18.
India was among the top 20 exporters of railways
globally, as of 2017. India’s exports of railways have
grown at a CAGR of 27.05 per cent during 2010-2017
to US$ 303.29 million. Exports of railways in 2018*
stood at US$ 278.05 million.
Investments/ DevelopmentsForeign Direct Investment (FDI) inflows into
Railways Related Components from April 2000 to
June 2018 stood at US$ 920.21 million.
Following are some of the major investments and
developments in India’s railways sector:
• In December 2018, France-based Alstom
announced plans to augment its coach
production capacity at its facility in Sri City from
20 cars per month to 24 cars per month. Also, it
will set up a new production line to increase
capacity to 44 cars per month by the end of 2019.
• In December 2018, the Prime Minister of India
laid the foundation stone for the third phase of the
Pune metro.

Few recent initiatives taken up by the
Government are:
• Government of India is considering a High
Speed Rail Corridor project between Mumbai
and Nagpur
• As of November 2018, Indian Railways is
planning to come out with a new export policy
for railways.
• The Government of India is going to come up
with a ‘National Rail Plan’ which will enable
the country to integrate its rail network with
other modes of transport and develop a multi-
modal transportation network.
• A 'New Online Vendor Registration System'
has been launched by the Research Designs &
Standards Organisation (RDSO), which is the
research arm of Indian Railways, in order to
have digital and transparent systems and
procedures.
• The Government of India has signed an
agreement with the Government of Japan
under which Japan will help India in the
implementation of the Mumbai-Ahmedabad
high speed rail corridor along with a financial
assistance that would cover 81 per cent of the
total project cost.
Road Ahead with Dedicated Freight Corridors:
The Indian Railway network is growing at a healthy
rate. In the next five years, the Indian railway market
will be the third largest, accounting for 10 per cent of
the global market. Indian Railways, which is one of
the country's biggest employers, can generate one
million jobs.
Indian Railways is targeting to increase its freight
traffic to 3.3 billion tonnes by 2030 from 1.16 billion
tonnes in 2018.
The major challenges are mixed Traffic with
differential speed, heavy congestion on IR routes,
inadequate powering of trains, lower priority to
freight trains, very low average speed leading to
increased wagon turn around time, low utilisation of
crew, rolling stock & locomotive, and energy -
inefficient locomotives leading to high energy cost.
With the introduction of rail networks exclusive for
freight movement, it is expected to provide a solution
for efficient and reliable freight operations, with an
objective to increase the rail share of freight
transportation not only from routine cargo but also
attracting non- conventional freight. In order to
boost the freight carrying capacity of Indian
Railways, the creation of two Dedicated Freight
Cortidors has been envisaged in first phase, along
the Eastern and Western arms of the golden
quadrilateral. DFC is expected to be a long term
strategic solution, with a view to increase the
declining rail share . This corridor is planned to have
high capacity, better infrastructure facilities,
scheduled services and premium service offerings
like guaranteed transit times, superior asset
standards when compared to existing freight system
of Indian Railways like axle load, locos, centralized
control system , all of which is critical for the shipper
in having rail as a preferred mode of transport. The
alignment of the freight corridor will be from
Ludhiana to Dankuni forming the Eastern Corridor
and from Dadri to JNPT forming the Western
Corridor of the alignment. Operations in DFCCIL is
proposed to be controlled through two tier system
with operating officers in Central Traffic Control
office at New Delhi, and Centralised Control office at
Ahmedabad for WDFC and at Allahabad for EDFC.
EDFC and WDFC controls will directly coordinate
with IR officers of respective Zones and divisions for
routine planning and actual running of freight
trains.
DFCCIL, an SPV established as a wholly owned
subsidiary of the Indian Railways, will develop,
construct, operate and maintain the corridor lines for
increasing the capacity of the railway network and
enable it, to efficiently carry an enhanced volume of
freight traffic. The freight corridors also provide a
platform to adopt international best practices in
terms of technology, design and business processes
which can be inducted on this new freight system.
The cost estimate of Rs, 81,459 Crs. for Eastern &
Western DFC including land cost has been approved
by the Cabinet Committee on Economic Affairs in
June, 2015. This comprises of construction cost of Rs.
73,392 Crs. (including Soft Cost of Rs. 19,390 Crs) and
land cost of Rs. 8067 Crs. The cost for the project will
be funded by a combination of debt from
bilateral/multilateral agencies, equity from
Ministry of Railways and Public Private Partnership.

The capital structure of DFCCIL will entail a debt
equity ratio of 3:1.
The DFC is part of a broader agenda of reforms in the
rail transport sector in India. The specific objectives
of the DFC are as below:
�Increase modal share of Railways in the freight
transport market by providing customised
logistics services
�Create additional rail infrastructure to cater to
growing freight transport demand
�Reduction of unit cost of transportation by
speeding up freight operations and higher
productivity
�Segregation of freight infrastructure for focused
approach on both passenger and freight business
of railways
�Introducing high end technology and IT packing
of freight services.
The freight trains of DFC will boast a 1.5 km length,
3660 mm width, a height clearance of 7.1 meter – the
first and only in the world. Moreover, given the
reduced time and cost of transporting freight, the
DFCs will aid the country in getting a competitive
edge in the exports market.
Some technical highlights of DFC: Automatic
signalling with 2km spacing between signals will be
used for both corridors. The Ludhiana-Khurja
segment of the Eastern DFC will additionally feature
an absolute block system. Traffic control
communications on the two corridors will feature an
independent OFC system. A GSM-R communication
system will be adopted for mobile train radio
communication.
Fully mechanized track laying :
Automated New Track Construction (NTC)
machines from Marsco (USA) and Plassers (Austria)
are being used for track lying. NTC Machine gives
high progress of track linking (upto 3 T-Km per day)
with better track geometry as compared to manual
lying.
High speed on loop lines :
Canted turnouts have been used to achieve speed
potential of 50 Kmph in yards.
Distressing track by super pullers :
Super pullers attached to ash butt welding machines
are used for distressing of track. Super puller can
carry out distressing at any rail temperature (lower
than distressing temperature) along with welding
thus obviating the need to wait for attainment of
particular temperature range for carrying out
distressing.
Indigenization of high technology equipment’s used
for DFCCIL electric traction.
100 MVA, Scott Connected Power Transformers are
being utilized in the Traction Sub-Stations of
Western DFC for 2x25 kV power supply. Similarly,
Auto Transformers of various ratings are also being
used in sub-stations and other switching control
posts. These equipment’s have been designed,
developed and manufactured under patented
technologies, by M/s. Toshiba Corporation and
M/s. Meidensha Corporation, both of Japan.
Under the ‘Make-in-India’ initiative facilitated
through the respective contracts, the Scott
Connected Power Transformer and Auto
Transformer are now being manufactured in
Toshiba and Meidensha factories in India, under the
transfer of technology (ToT) arrangement from the
original Japanese manufacturers. These have been
types tested in Central Power Research Institute
(CPRI), and have been supplied for the Western DFC
Project.
To protect and prevent the loss of malfunction of the
server data it has been recommended by a business
study that servers be located at multiple loacations to
cope with loss and malfunction of data in the event of
such incidents and use of remote servers such as
Cloud has been suggested due to ease of access
,maintenance and reduced costs. Network and
internet connectivity for voice and data
communication capabilities in addition to LAN
/WLAN capabilities have also been suggested as IT
support.
It is proposed to run standard trains of 750 m length
in the initial phases of the project life cycle. Also a
headway of 10 mints between trains and
maintenance block of 4 hours per day is envisaged as
standard operating parameters. A capacity
utilisation of 80% has been considered for estimating
the train operation on the DFC corridors which
translates into running of 96 trains per day
per direction in a section which is equivalent to 96
paths.

Globally running of longer trains is a common
feature, with 1.5 to 2.5 km in lengths, for carrying the
bulk traffic such as coal from mines or origin
clusters. Australia has one of the heaviest and
longest heavy haul trains in the world including
remotely located train control centres. Sis hen -
Saldana, iron ore export line in South Africa has a
train length of 4 km, consists of 342 wagons that
carry a gross train mass of 37000 tonnes, is hauled by
six electric locomotives and runs over a distance of
860 km. Following benefits are there of running long
trains :
�Reduction in operational cost per tonne with
savings in fuel consumption
�Achieving faster turnaround times
�Lesser congestion on routes facilitating easier
freight movement, reduction in detention
enroute and increase in speed of rolling stock
�Increase in throughput per train path
�Maximise payload per train path to increase
throughput
Density per train will obtain a soaring, in addition to
by running of long trains, with heavier trains, which
can be achieved also by running double stack
container trains. With DFC's operational efficiency
offerings, estimated traffic and other growth drivers
,it is essential to strategise handling of EXIM
container movement on Western DFC as this
corridor is expected to witness EXIM cargo
predominantly. It is proposed to operate double
stack container trains on the Western DFC, from the
day DFC becomes operational, so as to enhance the
throughput per train of the container trains, thus
reducing the number of paths required so as to
realise the goal of service reliability.
Promoting double stack container movement is
beneficial from cost perspective as well. However
,operating double stacked container trains also poses
certain operational challenges in terms of planning
at the point of loading as well as unloading so as to
al ign the container movement with the
upstream(port) and downstream (ICDs) handling
and logistics planning.EXIM traffic is the major
contributor of the estimated traffic with the critical
points being New Palanpur,New Mehesana, and
New Chadottar. Operating double stack container
trains has been proposed from New Palanpur to
New Dadri and other identified critical sections from
Mundra Port, Pipavav Port, JNPT etc. Further the
constraints of running double stack container trains
on IR feeder routes will have to be addressed in order
to make it more effective, by prioritisation of
upgradation of OHE on these feeder routes,
connecting to the Western Corridor, to allow
Maximum Moving Dimension (MMD) of 7.1 metres.
A common user terminal at New Prithala is planned
for double stacking, which can address the issue of
feasibility of north bound double stack container
trains to a great extent. Also connection from New
Dadri to Dadri ICD is planned which would be
critical as the EXIM traffic volume grows. The key
cluster for EXIM container is NCR cluster as origin
for up direction movement and destination for down
direction movement , with ICDs being located at
various places and being operated by CTOs like
CONCOR, Gateway, Hind Terminals, Adani, etc.
These CTOs can leverage the infrastructure
proposed to be provided by DFC. Various CTOs are
in process of getting connectivity with DFC network.
Over the years, coal has been the most predominant
commodity carried by IR constantly contributing to
more than 40% of the total movement. Coal Traffic
comprises the principal flow on the Eastern DFC
.This is so because a majority of of coal mines in India
are located in the Eastern region and coal produced
here is transported to thermal power plants located
in north i.e, UP, Delhi, Haryana, Punjab, Rajasthan,
Himachal Pradesh and, J&K. Some of the coal
produced in Chhattisgarh, Orissa and Maharashtra
also moves to the north. Movement of the
commodity on the DFC in future years is largely
dependent on the growth of thermal power
generation in the north and the colliery plant
linkages, which could also get revised after
commissioning of the DFC.
Apart from this, DFC as a new rail network
infrastructure presents an opportunity in terms of
capacity addition to offer non conventional freight
services which have been offered on the IR network
on a low scale owing to the capacity constraints.
These include RORO services, provision of mini rake
services etc. These will be classified as premium
service offerings and DFC as a service provider may
charge a premium for such services. These services
will help in attracting small shipments, reduction in
JUNE 2019DFCCIL JOURNALTh
e
34
transit time due to speed efficiency on DFC, saving in
fuel, tolls and other variable costs, use of depreciated
trucks in RORO, decongestion of roads and
reduction in emissions. Ultimately rail share will get
a fillip. RORO service is contemplated to operate in a
merry go round fashion from point to point and not
stopping between two junction stations. The services
will be time tabled. JNPT - Gujarat route clusters may
be potential starters due to high density of truck
movement and projected available capacity on the
DFC route.
It is proposed to procure Special Purpose Wagons by
IR for movement of freight on DFC to take advantage
of the infrastructure provided by DFC by increasing
the payload /carrying capacity per unit length of
train vis-a-vis tare load of wagon. Increase in
payload is expected to reduce energy consumption
per net tonne payload and O&M costs, in addition to
reduction in number of trains required for freight
movement leading to release of line capacity and less
congestion on routes. Additional cost incurred on
using lighter material like aluminium and its alloy, in
place of steel is expected to be recovered faster due to
increase in revenue earning potential of these
wagons due to high carrying capacity. In US, wagons
with carrying capacity of 120 tonnes to 130 tonnes in
four axle wagons are being used for freight traffic.
High capacity wagons are capital intensive in nature
along with the associated infrastructure required for
handling of such wagons. To facilitate private player
participation ,IR came up with a policy viz.
Libaralized Wagon Investment Scheme (LWIS),
wherein a private player, who may also be a shipper,
will invest in procuring high capacity wagons and
get freight discount of 12 % as per LWIS policy.
It is further considered that brake vans may not be
required on DFC network, as the network is
proposed to cater to freight only traffic and while
forming a long rake, brake van may be a weak link.
Internationally, also freight trains are fitted with
continuous braking as a result of which brake vans
have lost their importance and have been
discontinued by many railways.
A recent study on commercial and marketing
strategy suggests that in the standard Operating
scenario(750 Mtrs train length), both the corridors
would reach their capacity in the starting years of
operations. In the year FY 21 the projected traffic as
per this study are 134 trains in up and 121 trains in
down direction on Eastern DFC and 109 trains in up
and 128 trains in down over Western DFC. Therefore
running long rakes/double stacked rakes is a
necessity. Running long trains (1500 mtrs) would
help in releasing capacity. If the train length is
doubled and if it is assumed that all the trains would
be long length trains then number of trains would
reduce to half of projected. Studies have suggested
that profit margin % for most of the commodities on
DFC network will increase by 28% and 12% with
long train and with standard train respectively via-a-
vis cost on IR with standard train due to its designed
efficiencies and efficiency achieved in cost like
traction cost, crew cost, and faster wagon
turnaround. Further it is estimated that with long
rakes and standard headway of 10 mints, EDFC will
be saturated in FY 29, and WDFC is expected to
saturate in FY 24. After this capacity enhancement
can be achieved by reducing headway to 6-7 mints,
increasing train speed, bringing uniformity in train
speeds and lessening bunching of trains. The studies
recommend that based on identified critical sections,
the origin junction stations should have a provision
to form long rakes and the destination junction
station on DFC network should have a provision to
break the trains as standard length trains to move on
IR network. For this to happen yard at destination
junctions should have sufficient loop lengths to form
/break trains. For ensuring smooth operations on
DFC main lines, it is extremely critical to have
seamless operations on IR feeder routes connecting
to DFC main line network, as most of the traffic is
originating from and destined to IR network. Thus
synchronising feeder routes infrastructure in line
with DFC main line for seamless operations is
extremely critical. To ensure service reliability to
shippers it is necessary to minimise speed
differential among the trains, timetabling of trains,
an efficient operational coordination between IR and
DFCCCIL, and a good level of proactive and
preventive Infrastructure maintenance regime.
Freight market studies indicate that with healthy
operations parameters ,rail share within DFC
influence area has the potential to reach 47 % and
above in FY 21 and beyond with the commissioning
of DFC network.

DFC is further working on partnering with 3PL/4 PL
logistics players to provide end to end cost effective
and reliable services to the industries and for
developing, operating and maintaining PFTs and
MMLPs along the DFC alignment.
There are around 1835 terminals (Goods sheds,
PFTs, ICDs, Pvt Sidings) connected to IR, out of
which approx 170 feed traffic to Eastern and Western
Corridors. Out of 398 Mn Tonnes traffic projected in
FY 21 which will be attracted by DFC ,358 Mn Tonnes
will originate from existing IR terminals. Based on
terminal analysis it has been suggested by experts to
develop terminals at Nilje, Meerut, Mirzapur,
Shambhu (for Chandigarh/Shimla/Pantnagar/
Rajpura clusters) and Tundla (Agra cluster) by DFC
to optimise tapping of the traffic potential.
In order to capture the market DFC needs to employ
a combination of direct and indirect marketing
techniques to make the final customers aware of its
service offering. International best practices suggest
to develop a "Freight Calculator" and make this tool
available on the DFCCIL website to allow new
customers a quick check for the rail offering.
DFCCIL is working on this. Based on customer input
on type of freight, origin and destination, total
annual volume, frequency of traffic and additional
service level requirements the freight calculator
provides a quick calculation of availability, transit
time, frequency, service levels and carbon footprint
compared to other modes of transport. It also
provides on an informative basis a freight rate quote
to the customer and offers a direct contact to the
customer service centre. Such a tool can effectively
promote rail as a viable option and a price
competitive solution to new customers, which have
been reluctant in the past to consider the rail mode.
Commissioning of DFC will offload the freight
transportation burden from Indian Railway in a big
way and capacity will be released on Indian Railway
to run more passenger trains also, thereby easing the
passenger demands mainly for long distances which
is not addressed fully at present. More DFC
Corridors like East Coast and East West Corridors
are in the pipeline to be constructed in near future,
which hold promising future for freight movement
in India in more economic ways and with advance
technology. This will herald a new age making
the Indian goods more compet i t ive in
International market and reduce cost of
various products domestically.
Target for commissioning EDFC and WDFC is
March 2020. However, it is expected to start
commercial runs in some sections like Bhaupur -
Khurja, Ateli- Marwar in later half of 2019.

ELECTRIC TRACTION SYSTEM OVER WESTERN DEDICATED FREIGHT CORRIDOR (WDFC)
SYNOPSIS:
Western Dedicated Freight Corridor (WDFC) is
currently implementing the project having a
route length of 1504 Km with double line tracks. It
shall connect Dadri in Uttar Pradesh to
Jawaharlal Nehru Port Trust (JNPT) in
Maharashtra, near Mumbai. This article describes
the highlights alongwith key design parameters
of traction system being adopted over this
corridor. It gives an insight of 2x25 kV AT fed
high rise OHE with contact wire height of 7.54m
from rail level. The salient features, key
equipment used alongwith their ratings, merits,
demerits etc. of the system adopted are also
explained in detail.
Introduction:
The Dedicated Freight Corridors have been planned
in India with a prospective in mind that they are
designed to act as high capacity rail transit corridors
with several merging and demerging nodal points
on the Indian Railways (IR) network. Since IR has
standard train lengths of 750 m, the DFC Corridors
are designed as a high density corridors for handling
750 meter length (max 6500 metric tonne) and 1500
meter length (upto 13000 metric tonne) trains over
DFC networks. In addition to that, there is also a
need for running double stack containers of height
7.1 meter on WDFC, thereby, creating the need for
developing the traction contact lines at 7.54 meter
height, which in itself poses several challenges in
design, construction and operation of electric
traction system over WDFC. The salient key features
of route of WDFC are given in Appendix ‘Á’.
The selection of a single-phase or twin-phase system
depends primarily on technical and economic
aspects. When the load is relatively low and
electromagnetic interference does not impose much
constraints, the most commonly used 1 X25 kV
system is preferred due to its own advantages in
terms of lesser cost, ease in availability of
components, standard maintenance practices etc.
On the other hand, in case of heavy haul operation,
higher power density requirement, lesser
availability of space for traction sub stations or
where electromagnetic interference become a major
constraint in operation, then 2 X25 kV is the adequate
option for such corridors.
The electric traction system over WDFC has
accordingly been designed to cater for the above
requirements along with future incremental
loading/trains in the system. The traction system
JUNE 2019DFCCIL JOURNALTh
e
37
with 2x25 kV AT fed system has been adopted which
has a short time rating of 200% for 5 minutes and
150% for 15 minutes, in order to counter any sudden
surge in the train power demand in a particular
section for a short duration. The selection criteria of
electric traction system alongwith other technical
details are presented in the next section.
2.0 Electric Traction Power Supply System
The two most commonly used Power Supply
Systems for electrification on use worldwide are:-
• 1x25 kV System or 25 kV system
• 2x25 kV Auto Transformer Fed System
Although IR has got adequate experience in 1x25 kV
electric traction power supply system, which is
spread over Indian Railways, on the other hand, IR
has limited experience on 2x25 kV power supply
system, which is available only over a limited section
of IR. In 1x25kV system, a substantial portion of
return current in the range of 40 to 100% flowing
through the tracks and earth can create unwanted
electromagnetic interference to the adjoining
installations. This may cause electromagnetic
disturbances in cables in the vicinity of the line, if no
corrective measures are taken. As a consequence,
the cables need to be protected by cable sheaths. The
maximum line length to be supplied single-ended
from a substation is limited to approximately 25 KM
to comply with the tolerable voltage drop limits.
Accordingly, to overcome the above shortcomings
and in view of the following merits of the system,
WDFC has adopted 2X25kV system over its entire
network:
A. Higher Power Density
Since low currents flow through tracks and earth for
2x25 kV AC supply system in the sections between
the autotransformers, which are momentarily not
traversed by trains, the electromagnetic interference
will be much lower than in the case of 1x25 kV single-
phase supply system. Therefore, higher currents and
power can be transmitted which leads to increase in
capacity as well as performance of the lines. The
voltage drop is also lower for the same power,
thereby, enabling up to 50 km or more spacing
between adjacent TSSs. The WDFC has accordingly
been planned and designed to handle a power
density of around 1.5 Mega Volt-Ampere per route
KM. The traction sub stations having traction
transformers of 100MVA capacity are spaced 50-60
kilometer apart, in order to meet the high power
demand over WDFC network, against an average
TSS spacing of around 30-40 KM on 1x25 kV system
over IR network.
B. Lesser voltage drop
The 2x25 kV configuration utilizes Auto
Transformers to supply (+) 25kV to catenary wire
and (-) 25kV to negative feeder, thus essentially
providing a “boost” to the voltage on the overhead
contact system and extending usable reach of the
traction sub-stations.
The power is transmitted between the substation
and the auto-transformer preceding the section on
which the traction unit is collecting electric power
from the contact line as in a twin-pole 50 kV line. The
lower currents involved with this transmission of
power result in lower voltage drops in the overhead
contact line network even with heavier load
currents, thereby allowing more traffic in the
section. The voltage drop in case of 2x25kV system is
nearly half as compared to a conventional 25kV
system. As per study conducted by UIC, electrical
distribution efficiency for 2X25kV system is 97.6%
against efficiency of 92.95% in 1X 25kV system due to
substantial reduction in losses in the system.
C. Electromagnetic Interference (EMI)
Another major benefit of 2x25 kV Autotransformer
fed system is that the EMI emitted due to the load
current in the overhead system and running rails is
considerably reduced. This is primarily on account
of the fact that auto transformers inherently attempt
to equalize the current flowing in the two sections of
the auto transformers winding. This is also due to
the fact that traction power return current in the
running rail flowing through the Auto Transformer
(-25) kV winding and into the –ve feeder tends to
create the required balance. In the section between
two auto-transformers, the traction units are fed
from both ends, the rails serving as return
conductors in the customary manner. The
interference with adjacent lines is therefore also
lower than in single-ended feeding without auto-
transformers. In the section between the substation
and auto-transformer, the current flowing in the 0rails is low due to the almost 180 phase shift in the
overhead contact line and the negative feeder. The
interference with adjacent lines is therefore reduced
to a great extent.

Due to this, the current in running rails is much reduced between the train and remote auto transformer
feeding the electrical section and very much reduced in adjacent section. The effect of EMI generated in two
cases is shown in Fig.1 below:-
3.0 Details of 2x25 kV AT Fed Traction System
To improve transmission properties, the 2x25 kV, 50 Hz system is used for high-performance traffic in
worldwide railways. This type of feeding is characterized by additional auto-transformers and a return line
at a potential of( -25) KV. In this system, power is fed from the TSS at 50 kV and utilization is achieved at 25 kV
by providing Auto-Transformers of adequate capacity and by providing one additional conductor normally
referred to as a negative feeder wire. The center point of the Auto Transformer is connected to the earth/rail.
This arrangement facilitates +25 kV Voltage between OHE and rail and -25 kV voltage between Rail/earth
and the Feeder Wire. The spacing & capacity of autotransformers is decided based on the system design
capacity requirements and tolerable limits of the voltage profile, inductive interference levels etc. The traction
load is shared by both the adjacent ATs in inverse proportion of respective distances i.e. the AT nearer to the
locomotive will share more load than the farther one.
The basic design of this type of feeding along with flow of load current can be seen in Fig.2 given below:

The line supplied by a Scott Connected traction
transformer without center tapping. An additional
25 kV feeder line is required between the auto-
transformer stations and the traction substations.
The voltages between the negative feeder and the
rails and between the overhead contact line and the
rails are both 25 kV. The potential difference
between the overhead contact line and the negative
feeder is up to 50 kV. The substations need to be
designed for two phases instead of one. Because of
this, twin-pole switch gear is required in the
overhead line network. Also, the protection of the
contact line is more cost-effective because of the
double-phase design. Another major advantage is
that there is reduced unbalance on the utility
transmission network due to usage of three phase
traction transformer. The details of major
components of the system is as given below:
(a) Scott Connected Traction Transformer
2x25 kV Auto Transformer Fed Traction System has
been adopted over WDFC for optimum train
operation performance. WDFC has adopted Scott
connected, non-center tapped power transformer of
rating 60/84/100 MVA based on ONAN/
ONAF/OFAF mode of cooling to feed power to the
traction system. The transformers have been
manufactured both in Japan as well as in India by
M/s. Toshiba Corporation and M/s. Meidensha
Corporation respectively under the Transfer of
Technology (ToT) from the Japanese manufacturer.
The transformer has a voltage input on 220/132 kV, 3
phase, 50 Hz and the output has 2 secondary
windings known as main and teaser winding shown
below by M phase and T phase respectively in Fig.4.
The two windings are identical in voltage (25 kV),
Fig.3. Scott connected transformers and NIFPS system at Ringus TSS
Fig.4. Schematic arrangement of Scott connected transformer alongwith autotransformer
but with 90° phase displacement. The two windings,
viz Main & teaser, feed power on either side of the
TSS by supplying +25kV to OHE and -25kV to feeder
wire, thereby, maintaining rails at zero potential.
The neutral sections have been provided in OHE in
front of TSS. These traction transformers are also
fitted with Nitrogen Injection Fire Prevention and
extinguishing System (NIFPS) to prevent tank
explosion and fire prevention during internal faults
inside the transformer tank.
Fiber optic based temperature measurement of oil
and windings has been incorporated in addition to
the winding temperature indicators used generally
to detect transformer winding hot spots in real time
and activate the control of cooling system. Each
alternate TSS has been provided with necessary
future provisions for installing stand by traction
transformer. These transformers have been type
tested at Central Power Research Institute (CPRI),
Bangalore.

(b) Auto Transformer
The ratings of Auto transformers have been
calculated based on detailed simulation studies of
complete traction power supply system over
Rewari-Makarpura section of WDFC. Accordingly
these have suitably been provided at SPs, SSPs, and
Auto transformer Stations (ATSs) in order to
maintain the designed voltage profile of the
Catenary. In addition, because of adoption of non
center scott connected power transformer, ATs are
also used in TSS for providing rail earth midpoint
connectivity at the respective TSS as shown in Fig.4
above. The neutral terminal of the AT is connected
to rail. Such AT posts are located every 10 to 20 KMs.
The ratings of ATs chosen are 8.0 MVA, 12.3 MVA
and 14.3 MVA, 54/27kV and generally operated in
ONAN mode of cooling only.
(c) Catenary System
The catenary system consists of a catenary wire 2made of Copper-Magnesium alloy of 125mm , 2Contact Wire made of Copper-tin alloy of 150mm ,
2 current carrying flexible dropper of 10mm along
with associated jumpers etc.
2The negative feeder is 288mm all Aluminum Alloy
Conductor (AAAC), which has been strung on
separate feeder suspension arrangement on the
same mast. The Catenary system has been designed
for 940A current level and for a thermal loading of C100o .
(d) Cantilever System
A part of Cantilever requirement has been met by
modular cantilever system (MCS) (as shown in Fig.5)
which have been appropriately designed as per EN-
50119 standard and these have been fully type tested
for highest structural loading of each member.
Fig.5. Modular Cantilever
These cantilevers have been manufactured and
supplied by M/s. RIBE Germany. The major
advantage of these cantilevers is that these are made
of aluminum alloy tubes and aluminum casting
fittings. S.S. fasteners have been utilized to give a
longer life in field. These cantilevers are so much
light in weight that it is very easy to install/replace
them in field. However, major portion of the
cantilevers are based on the time tested IR cantilever
design, made from steel tubes and forged steel
fittings. The dimensions of cantilever tubes have
accordingly been designed to meet the required level
of loadings as per EN-50119 code. The tension in
catenary for both the wires has been kept at 12 KN
and the same has been regulated through five pulley
Auto tensioning devices manufactured by M/s.
Arruti Spain.
(e) Buried Earth Conductor
The earthing and bonding system adopted on WDFC
is quite different from IR. An Aerial Earth 2Conductor (AEC) of size 181mm of Aluminum
Conductor Steel Reinforced (ACSR) rigidly
connected with each metallic mast structure has been
provided.
Traditionally, the traction return current from
locomotive passes through rail, to the system
earthing point of the nearest traction sub-station. A
part of the return current also passes through the
sub-soil metallic structures, affecting the safety as
well as life of such structures, apart from generating
e l e c t r o m a g n e t i c i n t e r f e r e n c e i n n e a r b y
communication equipment.
In Western DFC, use of metallic Buried Earth
Conductor (BEC) has been adopted to act as a linear
earthing throughout the length of the track. The
Buried Earth Conductor (BEC) with 20mm diameter
galvanized steel wire has been buried under the
ground along the DFC track which helps in
mitigation of electromagnetic interference on the
corridor. The BEC is connected to the rails at approx.
every 400 meter apart, thereby, eliminating flow of
return current through the rails, thereby ensuring
safety too.
(f) Rail Earth Clamp
WDFC has adopted a new technique for effective
rail-traction bond connection, by use of a rail-earth
clamp, thus completely eliminating the drilling of
holes in the rails, or welding on rails. The clamp as
JUNE 2019DFCCIL JOURNALTh
e
41
shown in Fig.6 is rigidly fitted to the rails, having
sufficient contact surface area for effective passage of
the designed short circuit current. The assembly
consisting of test piece of rail alongwith the
clamping device has been subjected to short time
current withstand test at the appropriate value of the
short circuit current in Central Power Research
Institute. This will ensure safety and reliability of the
track structure, while meeting the mandatory
requirement of earthing and bonding in AC Traction
System.
(g) Auto Fault Locator
The auto fault locators have been provided at TSS
and other supply control posts where Auto
Transformers have been installed. It helps in fast
detection and troubleshooting of the fault in the
OHE. When a fault takes place on the OHE, the auto
fault locator identifies the location of the fault by
collecting the neutral current data of the two
adjacent AT posts. The neutral current data of
autotransformers is analyzed vis-à-vis the current
drawn from the source at the TSS and depending on
the ratio, the approximate distance of fault location is
calculated. The data so collected can be processed
further to arrive at the exact location of the fault. In
case of failure of AFL, SCADA is having the facility to
test the entire feeding section of a CB that has
tripped, to identify and isolate the faulty section.
(h) SCADA
The latest version of Supervisory Control And Data
Acquisition (SCADA) System has been adopted over
WDFC. There will be one Operational Control
Centre (OCC) situated at Ahmedabad, which shall
cater for the entire network of WDFC. The SCADA
will function as per TCP/IP based open protocol
following IEC- 60870-5-104 using dual redundant
communication channels. There will also be facility
to access SCADA HMI from remote location over
internet through necessary Firewall protection for
monitoring facility alone for the remote users as
shown in Fig.7. The architecture of SCADA system is
such that each RTU will be communicating with
OCC directly and independently, thereby, giving the
advantage that failure of one or more RTUs does not
affect the response time of other RTUs.
HUSKY make Remote Terminal Units (RTUs) have
been provided over WDFC for acquisition and
control of hardwired signals from various
equipment at each TSS. These RTUs can be
Fig.6. Rail earth clamp

e
42
programmed either locally or remotely using the TCP/IP based communication link. An engineering tool
known as Integrated Development Programme (IDE) has been used to configure SCADA offline and also
having features of database editing, graphics editing, topology editing, report editing etc, without interfering
with the functioning of online systems.
In total, although there are more traction power facilities required for a 2x25 kV Auto Transformers Fed System
than for a 1x25 kV systems, but there are fewer traction substations with their associated HV utility circuits, HV
transformer, HV switchgears etc. An aerial view of newly created Ateli TSS is as shown below:

A brief comparison of main features of OHE adopted over WDFC vis-à-vis being followed over IR is as given below:-

5.0 Conclusion
Due to higher loading requirements over WDFC, the adoption of 1x25 electrification system would have caused more OHE voltage drop, higher level of electromagnetic interference and higher voltage unbalance in the utility network. Due to less spacing of TSS and more no. of neutral sections, frequent switching ON/OFF of DJ/VCB of locomotive would also have been another drawback. Thus, the adopted system of AT fed 2x25 electrification system is an ideal solution, and most suited for the upcoming Dedicated Freight Corridors in India. This system shall definitely open a new era of technology and vast field of opportunities for Indian industry to manufacture the traction equipment suiting to the requirements of 2x25kV system. This shall prove to be a way forward for future traction systems to be adopted either for high speed rail or higher density traffic routes in India.

CONCEPT AND PHILOSOPHY OF FRICTION BUFFER STOPS
Veer Narayan, Vice President,
Project Management,Rlys and Metro Systra India
Sharad Kumar Jain, GGM/MA/EDFC-1
DFCC HQ
1.0 Introduction
Buffer Stops are provided at the end of overrun
lines in case a Train load overshoots the signals or
the train fails to stop to prevent the train load going
further and stopping/slowing down them
sufficiently to prevent the damage. Indian Railways
traditionally is using fixed buffers stops made of
Rails at dead end in Yards which are inadequate and
as a result there is the risk that moving train load
may collides with other train or overrides the end of
platform line or loop line. The use of fixed buffer
stops has become unsuitable due to their low
resistance and manner of deceleration, which is huge
if velocity is high. Fixed type buffer stop are allowed
only at those locations where very limited resistance
is justified in particular cases such as dead-end
tracks in shunting yard, rolling stock depots etc.
However these are not sufficiently strong to resist
the train loads. It is seen that most of the time these
fix end buffers fails whenever an over shooting train
hits it with good speed causing lot of damage not
only to dead end buffer but also to Rolling stock .
In the past there have been many accidents on
account of non-stopping of train load resulting in
serious financial losses or even loss of life. In one of
the accident in SC Railways, a train load overshot the
buffer stop and fell over the Road under bridge
leading to loss of lives of road users besides the
damage to the bridge structure. In the interest of
safety buffer stops of adequate types are required to
be installed in the system, else these fixed type buffer
stops will always be a safety hazard. With increase in
SYNOPSIS:
Buffer Stops are the important component of Railway System to prevent Unusual occurrence due to overshooting of the Train. Traditionally the Buffer Stop have been designed for very low speed. However, with the advent of higher speed of the loop lines and the higher capacity of the train there is requirement of installation of Buffer stop to handle the increased speed and load.
This article deals with the use of Friction Buffer Stops being provided in the DFCCIL System to handle the increased train load of 6500 MT and with higher Speed of loops of 50kmph. The Friction Buffer stops being provided in DFCCIL have been designed for 6500MT/10kmph parameter. This article deals with the various types of Buffer Stops, its design features, Philosophy and installation & Maintenance. Lately Friction Buffer Stop have been provided in Bhaupur – Khurja Section of EDFCCIL.

the speed of loops there is urgent need to install the
buffer stops of adequate design to resist the forces
coming due to overshooting of train loads. Fitting
efficient and effective end stop will protect
passengers train and rolling stock in the event of a
train failing to stop.
DFCCIL will be running the train of 6500 Mt
capacity with the loop lines designed for 50 Kmph.
Therefore it is necessary to Use high capacity Buffer
stops which can dissipate the impact energy safely
and without damage. The latest development is to
design buffer stops to dissipate the energy by
Friction. Sliding Friction buffer stops are the favored
construction of buffer stop, mainly due to its high
resistance and variations of layout These types of
Buffer stops which dissipate the energy of a moving
train load by means of friction are called Friction
type buffer stops with high resistance and high level
of safety. The design of buffer stops varies from the
train load and speed with varying train loads and
speed. Friction buffer stops have become the
preferred constructions at the end of a dead-end
track in railway stations abroad (e.g. Switzerland,
Germany )
2.0 Different types of End stops:Depending upon the mechanism to dissipate the
kinetic energy of moving train, the Buffer stops are
classified into three categories:
a. Sliding friction Hydraulic Buffer stop The sliding friction end stop is designed to
dissipate the impact energy in a controlled
manner via the sliding action of the friction
shoes fitted between the frame and rail profile in
conjunction with hydraulic energy absorption
system to provide a recoverable stroke for
impact up to 25 km/h and controlled sliding
distance for high speeds.
Figure –1: Overshooting of train due to inadequate Buffer stop
Friction shoes are located within fabricated ‘pockets’ on the end stops main frame these are fitted around the rail profile secured with three fixings to pre- defined settings to achieve the correct retardation value in relation to the design calculation. Each pair of friction shoes can achieve up to 50KN of braking force, the amount of impact energy to be dissipated will determine the number to be used.
Secondary friction shoes positioned behind the main unit can also be utilised to assist in dissipating the impact energy.
Anti climber shoe assemblies are also fitted to the front of the end stop main frame and clamped around the rail profile to prevent ‘uplift’ on impact. The friction shoes & anti climber shoe assembles are suited to most type of rail profile and can be reused after an impact – subject to inspection and in accordance with the user manual.
Figure-2: sliding friction end stop
b. Sliding ‘friction’ end stop – non-hydraulicTypical used on metro & main line – designed for
different Centre impact and side impact with
anti climber (if required). Pure friction only, the
number of friction shoes will depend on the train
mass, impacting speed and required
deceleration.
Figure-3: Sliding ‘friction’ end stop – non-hydraulic

c. Fixed end stop Fixed and stops are essentially ‘end of line’
systems with frame fixed directly onto the rails,
these type of end stops have no energy
absorbing ability unless used in conjunction
with hydraulic energy absorption system to
dissipate the impact energy. These systems also
have the ability to self-reset after impact.
Figure-4: Fixed and stops
3.0 Philosophy of Friction Type Buffer stops:
The sliding friction end stop is designed to dissipate the Impact energy in a controlled manner via the sliding action of the friction shoes fitted between the frame and rail profile. This can be used in conjunction with hydraulic energy absorption system to provide a recoverable stroke for impacts and controlled sliding distance for high speeds. Its manner of deceleration induced upon impact and during the braking makes it smart solution in railway transport safety. The general approach of designing buffer stops is via usage of the kinetic energy and its conversion into work. The main principle of working of Friction buffer stop is to dissipate Kinetic energy of moving train along the braking distance by friction force offered by buffer stop.
When the main braking frame is impacted, the energy is transferred to the Pair of friction shoes in the main braking frame, and the end stop will start sliding along the track to first 2 pairs of trailing friction shoes. If the energy is not totally absorbed at this point, the braking frame and 2 pairs of friction shoe will continue to slide along the track gradually absorbing the energy and reducing the speed. After sliding to the set distance that has been calculated any remaining energy will be absorbed by all pairs of friction shoes installed in the track and brings the train to a complete standstill.
The sliding friction shoe is a mechanical device
that clamps onto the rail track. The torque
applied to the tightening bolts of the friction
shoe determines the amount of clamping force
applied to the rail track. In order to move the
friction shoe along the trail track the torque
induced static friction must be overcome. As the
shoe slides along the rail track the dynamic
friction of the shoe must be overcome and is
typically less than the static friction. The distance
that the friction shoe slides is a function of the
kinetic energy of the impacting mass. The kinetic
energy of the impacting mass therefore is absorbed
by transformation of heat energy at the friction
faces and subsequently dissipated to the
atmosphere.
A friction type Buffer stop consists of three parts:
a. Buffer stop Frame- to resist impact
b. Friction shoes- to provide frictional forces.
c. Length of Railway track- on which frictional
shoes move to dissipate Energy.
d. Anti Climber shoe assembly- to prevent uplift of
the Buffer stop frame .
2.1 Buffer stop Frame: The frame is designed to
withstand the impact load from the moving train
and transfers it to the Friction shoes. It is made
according to the type of coupler and is designed
accordingly. As one of the effect is to overturn, it
is fitted with Anticlimber shoe at the front side.

2.2 Friction shoes: These are the main energy dissipating device. It holds the rail and on the force of train
load slides with the frictional force between the rail and it. The sliding of friction shoes generates the
heat which then dissipated to the atmosphere. The sliding force can vary from 25 KN to 100 KN depending
upon the design.
Figure -6: Friction Buffer Shoe with anti climb Stopper
Figure -7: Friction shoes
2.3 Railway track to provide sliding: As the kinetic energy of the moving train is dissipated through the
frictional heat energy due to sliding of the frictional shoes, the length of track for sliding has to be kept . the
track over which sliding has to be done should be sufficiently stable to handle the longitudinal forces due
to slide of the frictional force. Usually the track structure provide is continued for the adequate length.
2.4 Anti-climber shoes: When the main braking frame is impacted, there is uplift force over the frame as the
application of force is at some height. This induces the overturning moment which is resisted by the
anticlimber shoe ( as shown in fig 1) . The anti climber shoe is provided in the front of the frame to anchor
the buffer frame against overturning.

4.0 Design Principles of Buffer stops:
Design principles are being explained to make the
readers understand the basic concepts. It is not done
into the details of design of each component.
The various parameter that govern the design of
Buffer stops are as below:
a. Mass of train
b. Speed of the train
c. Maximum average deceleration permitted
d. Friction Element sliding force
Mass of the train and speed of the train decide the
value of the Energy to be dissipated by the Buffer
stop. The maximum average deceleration
permitted decides the maximum nos of friction
shoes to be permitted to be moved as the larger
number of shoes will increase the deceleration.
Energy to be dissipated is determined by well
known formula of Kinetic Energy of a moving
mass which is equal to ½mv2.
Energy dissipated by friction shoes is equal to F*S.
Resistance of a friction buffer stop (work of the
buffer stop) could be much higher than a fixed
buffer stop, and can be customized for various
train mass, trains speeds and acceptable
deceleration rates. There is no disadvantage of a
friction buffer stop except slight more
requirement of space due to its braking
distance.
So depending upon the total Kinetic Energy and
the frictional force of the slide shoes the distance
of sliding is calculated which is provided in the
field. As given in the Figure 4 the friction shoes
are provided at the spacing to accommodate the
sliding.
Deceleration rate could be the limiting
parameter when designing number of braking
jaws and their braking distances. The most
challenging design comes with dead-end track
where limited braking distance available
Deceleration rate has to be monitored both upon
impact and along the braking distance where
additional braking jaws could be designed.
Fortunately, restriction in deceleration rate
applies only to the passenger trains where it
should be low from safety point of view of
passengers. such is not the case in DFCCIl
The objective is to design the number of braking
jaws and their braking distances. There are two
possibilities how to design the friction buffer
stop:
1. friction buffer stop without additional braking
jaws
A typical layout of a friction buffer stop is as below:
Figure -8: typical Layout
JUNE 2019DFCCIL JOURNALTh
e
50
2. friction buffer stop with additional braking jaws
For better understanding of the deign concept
the design followed in one of the Buffer stop in
DFCC is explained below.
Mass of the train: 6500 MT or 65,00,000Kg
Velocity : 10 KMPH or 2.78 m/sec
K.E. to be dissipated (½mv2): 2,50,77,160 Nm
Work of the braking jaws can be obtained using
Formula work = friction force * distance.
Friction force is provided by friction braking
jaws & therefore number of jaws can be worked
out by knowing friction force provided by one
pair of braking jaws. In the friction buffer stops
the Friction force of one pair of shoe is designed as
50 KN.
we have provided 10 pairs of jaws in frame
followed by 4 pairs of jaws at 30cm and 4 pairs of
jaws at 30 cm and finally 3 pairs of jaw at 30cm.
i) During first impact, 10 pair of friction buffer
offer resistance for 30 cm( 0.3m) of sliding
distance.
Energy dissipated- 10*50000*0.3=15000 NM
So balance energy left to dissipate = 25077160-
150000=2492760 NM
ii) After first movement of 30 cm , next 4 pairs
comes in force & thus 14 pair moves to 30 cm
sliding distance
Energy dissipated- 14*50000*0.3=210000 Nm
So balance energy left - 24927160-21000=24717160 Nm
iii) After next 30 cm , 4 more pairs comes in action
Energy dissipated- 18*50000*0.3=27000 Nm
Balance energy left-24717160-210000=24447160 Nm
iv) After next 30 cm ,another 3 jaws comes in action and
Frictional force- 21*50000 =1050000N
Balance Energy to be dissipated- 24447160 NM
So braking distance required to dissipate balance
energy of 24447160 Nm- 24447160/105000=23.28 m
so length of track required beyond Buffer point is
23.28 + 0.9=24.18m
Length of 11 pair of buffer @ 210 mm each =2.3 m
Buffer stop structure length =3.2 m
Thus total length of installation required 24.18
+2.3 +3.2 + 29.68 m
Spacing and number of friction buffers can be
changed depending upon length available for
braking distance beyond location of buffer stop
5.0 Installation and maintenance of Buffer Stops at Site:
Following are the important aspects to be kept in
mind while installation and maintenance of Buffer
stops at site:
a. Frame must be sufficiently strong to withstand
the impact force
b. Anti-climber shoes to have the sufficient
anchorage to prevent overturning. Tightness of
the bolts to be ensured.
c. Frictional shoes should be ensured to have
sufficient frictional forces. Tightness of the bolts
to be ensured.
d. Surface of rail should be dry to provide the
requisite friction.
e. Buffer stops should not be in down slope
direction as it will increase the force to be
resisted.
f. Track in advance and rear of the friction buffer
should be well compacted and consolidated to
provide the resisting force.
g. Formation below the track should be stable as it
will finally resist the forces. The high forces
induced due to friction of shoes sliding may
necessitate the construction of RCC slab to resist
the forces coming over the system.
Friction Buffer of capacity 300 MT /10 KMPH
have recently been provided in DFCC Khurja-
Bhaupur section. Friction buffer stops of higher
capacity of 6500 MT/10 KMPH will be provided
soon. These are first of its kind in India in terms
of its capacity to resist load.
6.0 Conclusion:
The usage of the fixed buffer stops in the railway
stations is slowly becoming an anachronism. With
the advent of coming of railway systems with high
axle loads and higher speeds in main and loop line,
there is requirement to design the buffer stops
adequate to resist the coming forces to ensure safety
of train operations. Friction buffer stops with high
resistance and high level of safety meet those criteria.
The possibilities of varieties of designing the friction
buffer stop is the huge advantage as it can be
designed for the range of options from light trains
with low collision speed, up to heavy trains with
high collision speed. We expect to see more such
types of Buffer stops in future in Indian Railways for
greater safety.

MoEF&CC: Forest Clearance Demystified
1.0 Forest (Conservation) Act, 1980 : – Keeping in view the widespread diversions & damage to the forests in the country (diverted at the rate of 1.50 lakh hectare per annum by the various State Gov./UT), Forest (Conservation) Act, 1980 was enacted. It has come into force on the 25th day of October, 1980.
The Act is a unique piece of legislation and a regulatory mechanism that reflects the collective will of the nation to protect its rich biodiversity and natural heritage and permits only un-avoidable use of forest land for various developmental purposes. The remarkable feature of this Act is that it is regulatory and not prohibitory. After enactment of this Act, diversion came down to 0.38 lakh hectare per annum after 1980.
Under the Act, no State Government or other authority can make, without prior approval of the Central Government, de-reservation of any reserved forest; use of any forest land or any portion for any non-forest purpose; lease to private person/
authority/ corporation/agency and clearing of trees
grown naturally etc. Any offence under this Act by
any authority/person/Dept. of Govt. or any
authority shall be liable to be proceeded against and
punished accordingly.
2.0 Online Portal:- A portal named as “Pro Active
Responsive facilitation by Interactive and Virtuous
Environmental Single Window Hub” (PARIVESH)
has been developed by MoEF&CC for processing of
all online applications by the user agencies for
seeking forests, environment and wildlife
clearances. It has also been mandated that
applications for various clearances should be
submitted only online. No offline application is
being accepted by Forest Authorities. It automates
the entire tracking of proposals which includes
onl ine submissions of a new proposal ,
editing/updating the details of proposals and
displays status of the proposals at each stage of the
workflow.
SYNOPSIS:As Railway projects are running in all parts of the country, it is facing forest land in the midway. Forest (Conservation) Act, 1980 has come into force on & from 25.10.1980. The Act was enacted to save the environmental impact of mindless diversion of forest areas. After enactment, rate of diversion of forest land has come down from 1.50 lakh hectare per annum to 0.38 lakh hectare per annum. After enactment large number of projects got caught for want of forest clearances. Due to non-availability of details and complex structures created in the process for clearances, project controlling authorities are running from pillar to post for getting forest clearances. The instant paper is an attempt to simplify the entire process of forest application and make it simpler for understanding and application in the field. This has demistified the entire process of forest application which prima facie seems to be hard nut to crack.

(Ref – Figure 4)
3.0 Compensatory Afforestation -
Compensatory afforestation (CA) is one of the most important requirement/ condition for prior approval of the Central Government for diversion of forest land for non-forest purposes. The purpose of compensatory afforestation (CA) is to compensate the loss of 'land by land' and loss of 'trees by trees'. Normally, CA is to be raised on suitable non-forest land, equivalent to the area proposed for diversion, at the cost to be paid by User Agency. The non-forest land for CA is to be identified contiguous to or in the
JUNE 2019DFCCIL JOURNALTh
e
56
proximity of a Reserve/Protected Forest to enable
the Forest Department to effectively manage the
newly planted area. Where non-forest land is
available but lesser in extent to the forest area being
diverted, CA could be carried out over degraded
forest twice in extent of the area being diverted.
4.0 Net Present value –
The concept of Net Present Value (NPV) was
introduced by Hon’ble Supreme Court of India by its
orders dated 29.10.2002. The Net Present Value
(NPV) of forest land diverted for non- forest
purposes is also to be recovered from the user
agencies, for undertaking forest protection, other
conservation measures and related activities. This is
payable once demand is raised by DFO after Stage-I
clearance is received.
5.0 Status of Forest Proposals under KKK unit –
Out of total nine (9) districts in the unit, forest lands
are involved in five (5) districts. Total forest land
involved is to the tune of 427.12 Ha which is
approximately 35% of total land requirement. The
details of the forest proposals with current status are
made available in Figure 5. The tabular data in this
Figure 5 are:

GSM-R System for Western Dedicated Freight Corridor
1.0 History of GSM-R :
The early nineties saw about 35+ railway
communication systems being used across Europe.
There were wired / cable and analogue radio
networks which were not compatible with each
other. That’s when the European rail companies
thought of standardising the communication for the
railways.
The concept of Communication system based
signalling was being preferred. Railways wanted to
adopt a proven technology with minimum
modifications. Two potential technology candidates
were identified GSM-R and TETRA. In 1990, TETRA
was still in the standardisation process whereas
GSM-R got an overwhelming support from the GSM
industry, thereby, promising to create a wider
ecosystem. Being a proven technology with an
overwhelming support from the GSM industry, it
was chosen as a standard for Railways.
For commercially adapting GSM based standard for
railways, the European Integrated Radio Enhanced
Network (EIRENE) project was initiated in 1992 by
UIC. The aim of the EIRENE project was to develop
speci f icat ions for a GSM-based rai lway
communication network. The EIRENE project ended
in 1995 with publication of Functional Requirements
Specification (FRS) and System Requirements
Specification (SRS). The EIRENE project was
followed by Mobile Oriented Radio Network
(MORANE) project, whose goal was to run three
GSM-R networks for testing and validating the
performance of the technology. This project finished
in 2000, with a delivery of the final specifications of
GSM-R.
The success of GSM-R is largely attributed to the
allocation of spectrum to the European countries
allocating the same 4MHz spectrum across Europe
(876–880 MHz is the uplink band, while 921–925
MHz is the downlink band). The common band used
across the whole EU is one of the important elements
allowing for “cross-border interoperability”. Later
in some countries GSM-R received an additional 3
MHz spectrum (873–876 MHz for uplink and
918–921 MHz for downlink). Thus, a total
bandwidth of 7 MHz is available for GSM-R in those
countries. Today 60+ countries have adopted GSM-

R as a standard to cater to the basic “Mission Critical”
needs of its railway organisations.
GSM-R has become a mature and secure global
railway standard. It caters to the basic needs of any
global railway organisation namely:
a) Safety
b) Proven technology
c) Standardised for Railway use
d) High Reliability and Availability
e) Communication at high speeds ( ~500 Km/hr)
f) Cross Border Interoperability
g) Us ing s tandardised ecosys tem (e .g .
transmission, Handsets etc.)
h) Support of Railway specific services
i) Integration of Railways Communication &
Signalling systems
2.0 Global Status of GSM-R Today
Wireless technology in commercial networks is
taking a giant leap moving from GSM (2G) to 3G to
4G to 5G.On the other hand, globally, railways are a
conservative technology adopter due to its Safety
concerns and are slow to adopt any technological
changes. In the recently concluded INNOTRANS
2018 (Berlin) most of the GSM-R equipment
providers have shown their affinity and confidence
in GSM-R technology. They are committed to
support it at-least till 2030/35. Some Countries as
recently as in 2018, floated a tender for countrywide
deployment of GSM-R. Poland, Germany, Hungary
are some of the nations that have plans for expansion
of their existing GSM-R networks. Countries like
Saudi Arabia, UAE etc. are in the process of
expanding their GSM-R networks. Indian Railways
too has awarded multiple GSM-R contracts and is in
the process of phased deployment of these projects.
3.0 GSM-R System for Western Dedicated Freight Corridor - Phase 1
The Western Dedicated Freight Corridor (WDFC)
Phase-1 Project comprises approximately 915 km of
double line electrified railway track with 2x25kV
AC, 50Hz overhead catenary system from Rewari to
Makarpura. GSMR deployment mandates to
provide ground to train voice and data
communication and vice versa, thus addressing the
mobile communication needs of maintenance staff,
track side workers, station and ELMD staff and
railway administration and management staff.
The network being deployed has the NoBo
certification of EIRENE Standards. It has certified
interoperability with the incumbent GSM-R network
of Indian Railways.
The network consists of various network nodes
belonging to either of the categories
a) Core Nodes.
b) BSS (Base Station Sub System) Nodes.
c) O&M (Operation & Maintenance) Nodes.
d) VAS ( Value Added Services) Nodes.
e) User Equipment.
3.1. The WDFC Core Architecture is as shown below:

All Core nodes shall be co-located in the OCC
building planned at Ahmedabad. The traffic
carrying core nodes are carrier grade and fully
redundant built on the OEM (Kapsch CarrierCom)
technology. This is the first deployment of IP based
R4 Core in Indian Railways in the Country.
The core comprises of various nodes like MSCS (Mobile Switching Centre Server), HLR ( Home Location Register), MGW ( Media Gateway ) and a
very powerful IN / SCP (Intelligent Network or
Service Control Point ). All the core nodes are
connected on IP via internal high availability fully
redundant LAN ( Local Area Network ).
MSCS supports the voice switching of the channels
and support implementation of all the telephony
supplementary features (Call wait, Call Hold,
Calling Line {Presentation etc.)
Figure 1:WDFC Core Network

HLR is the fully redundant high availability database that facilitates the creating and storage of profiles of all the subscribers created in the network.
MGW is the gateway that provides connectivity between the Core & the BSS nodes. It facilitates the conferencing facility also. All TDM nodes like EPABX and dispatcher are connected to this node. Provisions have been made to enable connectivity to RBC nodes of ETCS level 2 in the future.
IN/SCP system is the key to implementation of railway specific features like FA (Functional Addressing) , LDA (Locat ion Dependant addressing), CSAM (Call Screening and Access Matrix) to name a few.
SGSN & GGSN are key to deploying GPRS functionality in the network. It is the first deployment of GPRS in any GSM-R network in Indian Railways. The GPRS along with CSD (Circuit switch Data) is making the core fully ready to support ETCS Level 2 signalling.
3.2 BSS comprises of the following Nodes:
• BSC (Base Station Controller)
• TCU ( Transcoding Unit )
• BTS (Base Transceiver Station)
• PCU (Packet Control Unit)
BSC performs various functions like BTS supervision, Radio channel allocation, Radio channel monitoring, Traffic management, TCU management, OMC-R link management, Handover procedures etc.
TCU provides connectivity of the BSS nodes with the core nodes. It manages the TDM (Time Division Multiplexing) between the Core nodes & the BSS nodes. It configures and monitors the PCM links on the A and Ater interfaces. It performs coding / decoding of the speech frames and rate adaptation of data frames.
BTS performs channel coding/decryption. It contains transmitter and receivers, antennas, the interface to the PCM facility and signalling equipment specific to the radio interface in order to contact the Mobile User Equipment. It processes the signalling and speech required for Mobiles in air interface at one side (via antenna) and with BSC in Abis interface (through PCM 2Mb/s in OFC network) at the other side.
BTS network has been designed keeping in view the introduction of ETCS Level 2 in the near future. It is the only BSS network in the country which will be ETCS Level 2 ready. The media connectivity
between the BSC and the BTS is redundant and in
loop architecture comprising of 4BTS per loop. Overlapping coverage has been designed (discussed in the later section) which has been done for the first time in the country for railways.
Fully redundant PCU connects the BSC to SGSN on
IP to enable GPRS.
BSS Architecture
3.3 O&M Nodes (Operation and Maintenance)
All the nodes being provided will be centrally
monitored from the OCC. OEM has proposed a high
availability carrier grade O&M platform with full
FCAPS (Fault, Configuration, Accounting,
Performance and Security Management)
functionality.
3.4 VAS Nodes
SMSC (Short Message Service Centre) has been planed for deployment for the first time in a Railway GSM-R network in India for sending
messages between various User Equipment.
VRS (Voice Recording System) Voice Recording of
all the calls on the GSM-R network is being provided
to help the railways in any kind of an unfortunate
disaster situation.
Latest state of the art IP Dispatcher system is being
deployed for railway operations. IP dispatcher is being deployed for the first time in India in a GSM-R environment. The system is fully
redundant, capable of sending and receiving SMS
messages and 100% recording of calls.
3.5 User Equipment
The network is capable of supporting all the certified
and interoperable GSM-R devices available
globally. OPH (Operational Purpose Handsets) are
being provided for the operational staff on ground

and On- Board. OPS (Operational Purpose Shunting
Handsets) are being provided for the shunting teams
on the ground. Cab Radios are being installed in the
locomotives for the ground to On-board loco
communication. Cab Radios are 8W radios with high
sensitivity which are used by the Loco pilots. For
communication with stations FRT (Fixed Radio
Terminal ) with external antennae on the station
buildings are being provided.

4.0 Radio Frequency (RF) Design of WDFC’s GSM-R Network
The purpose of the Radio engineering activity is to define quantity and locations of radio sites based on project inputs and assumptions. The nominal final number of sites are determined after a complete environment survey and dedicated CW measurements campaign along the lines. Customer specific requirements for sites locations, frequency availability, coverage targets are taken into account before to start the radio design. In addition, local rules, regulations and laws lead to modifications in the site characteristics, including, but not limited to, sites location, height of tower or EIRP. All of these factors will affect performance of the radio sites.
The RF Design process follows a series of steps as detailed below:
• Definition of coverage, traffic and performance objectives
Figure 4:Cab Radio
• Acquisition of Digital Terrain Map and Setting up Planning Tool
• Environment Surveys
• CW Testing and Propagation Model Calibration
• Link Budget Definition
• Nominal RF Planning
• Site Acquisition and Build
4.1 Definition of Coverage, Traffic and Performance Objectives
The radio system is based on GSM-R technology as defined in the EIRENE recommendations. DFCC has specified compliance to the EIRENE system requirements and certain radio targets/ specifics. These requirements form the basis for the design. Some of the salient requirements of the Bid are listed below:
• RF coverage along and around 250 m of the railway track along the WDFC alignment from Rewari to Makarpura.
• Maximum inter site distance of 7 kilometres.
• BTS at every junction and crossing station.
• R F s i g n a l l e v e l s a s p e r E I R E N E recommendations (-95 dBm at 95% coverage probability). Further, a signal threshold of -80 dBm has been specified for providing coverage to handhelds considering an in-train penetration loss of 15 dB.
• Overlapping coverage from sites on either side to cater to failure on an intermediate BTS site (fault tolerant coverage) for the case of cab radios inside the locomotive.
• Design maximum train speed of 220 km/hr.
• The radio system to operate in the frequency band 952.8-954.4/907.8-909.4MHz (with eight channel allocations).
• Radio system to be equipped with 15 traffic channels and one control channel or 14 traffic channels and two control channels.
• The network should support point-to-point data communication. The network shall support data rates of at least 2.4 kbit/s.
• Maximum tower height of 40 metres.
4.2 Digital Maps
The RF design tool uses a digital map database created from various source inputs (like SOI topo maps) and updated with high resolution satellite
JUNE 2019DFCCIL JOURNALTh
e
63
imagery (20m resolution). The digital maps are created as layers and indicate land use (clutter), terrain
(heights) and vectors (roads, railways etc.). The maps have been updated with kmz files provided by DFCC to
create the WDFC route. A buffer zone of 10 kms on either side of the DFCC railway track was incorporated
into the digital map.
4.3 RF Planning Tool
The design was performed using a coverage
prediction approach using the Atoll tool from Forsk
(version 3.2.2). The tool uses various databases like
the digital maps, the site database (site coordinates,
antenna heights, the antenna patterns, antenna
orientations etc.) and the propagation model to
calculate the losses at each point in the digital map.
These are converted to coverage and interference
plots knowing the radiated power from each site.
The losses at each point are calculated on the basis of
a propagation model which is calibrated for the
specific environment.
4.4 CW Testing and Propagation Model Calibration
CW measurements are performed to tune the
propagation model so as to provide coverage
predictions close to the real world environment. The
way the signal propagates varies from environment
to the other. The signal propagation will be different
within an urban area and than in a rural setting.
Therefore, the first step is to identify the various
types of environment that will be primarily
Figure 5: A Sample of She Digital Map Showing Clutter, Vector and Terrain
encountered in the area of interest. For each
representative area, CW measurements are
performed at multiple locations along the route for
each environment type to collect signal strength
samples. All measurements are geo-referenced.
Signal samples so collected for various
measurement points are imported into the radio
planning tool and used to calibrate the model by
tuning the K1, K2… coefficients within acceptable
limits of statistical error (RMS mean error close to
zero and standard deviation < 8 dB).
The following types of environments were identified along the track:
Open Flat Area: These are environments where the
terrain is flat and there is little or no vegetation.
There are few obstacles to signal propagation.
Urban and Industrial Zones: The environments in
and around cities are classified and urban (low,
medium and dense). The industrial areas have
typical factory sheds, buildings or warehouses.
Buildings close to the railway track create diffraction
effects that cab affect signal propagation.

Hilly Areas: These are areas where there are low
hills and some vegetation near to the railway
track. Diffraction effects come into the play.
On the basis of this, a total of fifteen CW
measurements locations all along the track were
chosen cover these three environments to develop
suitable models. Of these, six were in Open Flat,
six in Dense Urban and three in Hilly areas.
The test set up consists of the transmitter
connected to an omni-directional antenna on the
transmit side. On the receive side, a receiver and
GPS are connected to a data logging PC. The
receive antenna and GPS antenna are mounted on
the rooftop of the vehicle.

On the basis of the calibration procedure described
above, three tuned models were developed to be
used for railway projects in India:
• India_Model_2018_Open_Flat
• India_Model_2018_Dense Urban
• India_Model_2018_Hilly
4.5 Link Budget Definition
The link budget is used to compute the maximum
path loss corresponding to a specific equipment
configuration and application. It is based on a path
loss calculation between the BTS (transmitter) and
the mobile (receiver). Two path losses are calculated:
the uplink path (Mobile to BTS) and the downlink
path (BTS to Mobile).
The inputs needed to perform this calculation are
organized in three categories:
• The general parameters (BTS related, antenna
heights etc.) that will be independent of the kind
of service.
• The parameters that will depend on the kind of
service (e.g. mobile type).
• The engineering margins that will depend on
the kind of service and the speed of the train and
which ensure that the required QoS is met. The
design requirements of maximum train speed
etc are accounted for considering an
overlapping margin herein.
Useful outputs of the link budgets are the
balanced EIRP (based on a link balance being
maintained) and the outdoor minimum field
required to meet the coverage objectives.
Typically it is necessary to provide coverage to
different types of mobile equipment
configurations. In accordance with the
equipment types defined and the service to be
provided, the worst link budget is calculated
and the worst case is considered.
This means that if we dimension the link budget
on the worst case, the requisites of the best case
will be, obviously, satisfied.
Two types of link budgets were developed to
cater to the cab radio and handheld case.
4.6 Nominal RF Planning
GSM-R coverage is mostly linear and sites are
located close to the railway track, and, at times some
of the railway infrastructure is also reused.
The coverage for the entire DFCC track has been
planned with a single radio layer with high degree
of overlapping (to cater to the fault tolerant coverage
requirement).
As mentioned earlier, the coverage design has been
performed using Atoll (version 3.2.2). The BTS
equipment chosen for the design was the BTS 9000
from OEM. Two types of cross polarised antennae
were used for design purposes- a 20 dBi/ 30°
beamwidth (80010456v02) and an 17.4 dBi/65°
beamwidth (80010306 v02) from Kathrein.
4.7 BTS Coupling
The BTS is connected to a set of 2 sectorized antennas
to provide a single cell within a BTS omni
configuration. The resulting mono-cellular
configuration with sectorized antennas avoids a
handover beneath the site and improves the overall
quality of service.
Figure 9: BTS Coupling Scheme
65
JUNE 2019DFCCIL JOURNALTh
e
66
This ensures one unique cell within a BTS omni configuration (O1+1 or O2 with 2 TRX). Cross polarization
diversity will be for the coverage of this line. The 2 antennas are set on each side of the tower and are
connected to the 2 receiver paths of the BTS to ensure diversity reception (Rx main and Rx diversity).
4.8 Coverage Predictions
The design tool uses the digital map database in conjunction with the site database, transmitter database and
the prediction model parameters to create an array of predicted coverage per bin for the entire digital map
database. User defined variables are the site locations, antenna types and heights, antenna orientations and
tilts. A sample of the coverage maps is shown below: it shows the cab radio coverage threshold (in green) and
the handheld coverage (in red).

4.9 Frequency Planning
The objective of frequency planning is to allocate the channels in an efficient way to cater to the traffic
requirements whilst minimizing the overall co-channel and adjacent channel interference in the network.
The frequency band allocated by the standardization body ETSI to GSM-R is [876 MHz – 880 MHz] in uplink
and [921 MHz – 925 MHz] in downlink. The spacing between two consecutive channels is 200 KHz. Therefore
19 channels are dedicated to GSM-R.
As per the spectrum allocated to IR only 8 channels would be available in public GSM 900 MHz band. The goal
of the frequency plan is to minimize the level of interference, as the same limited set of 8 radio channels is
reused in the entire network.
ARFCN Uplink Downlink ARFCN Uplink Downlink
89 907.8 MHZ 952.8 MHz 94 908.8 MHz 953.8 MHz
90 908.0 MHz 953.0 MHz 5 909.0 MHz 954.0 MHZ
91 908.2 MHz 953.2 MHz 96 909.2 MHz 954.2 MHz
92 908.4 MHz 953.4 MHz 97 909.4 MHz 954.4 MHZ
Figure 12: Frequency Reuse Plan
The frequency plan for the DFCC network will have a four cell reuse pattern. The eight frequencies allocated
above were be grouped into four sets, with at least 400 KHz separation within a cell and between
neighbouring cells. Each cell would have two allocations and hence two TRX’s.

Figure 14: C/I Plot Sample
For ETCS implementation in the future, it is recommended that the frequency spacing within a call be 600
KHz and that between neighbouring cells in maintained at 400 KHz. Consequently, more spectrum will be
required
5.0 Conclusion and Recommendations The design objectives for the DFCC network have been met with a
core network comprising of an R4 MSC core, IN, GPRS nodes, OAM and BSC equipment slated for
deployment at the OCC in Ahmedabad and a total of 172 sites (including the coverage of the OCC site). A
substantial number of ALH (auto location huts) locations have been reused in the design, which will result in
substantial CAPEX and OPEX savings. Tower heights have been maintained for the most part to be below 40
metres (with maximum tower height limited to 35 metres). The calibrated models developed for the STP5
network design will help in designing future networks of the DFCC GSM-R networks in India. Since the
WDFC network is ETCS Level 2 ready, the network can be easily used for piloting the same, provided, more
spectrum is made available, in the same band.

F) Construction Operation:
a ) Clearing and Grubbing of Natural Ground:
Cleaning of the natural ground is carried out
for removing the Roots bushes branches,
organic and all types of substance except Soil
from ground. Prior to start of activity of C & G,
Natural ground levels are jointly recorded.
After the completion of C & G, final levels are
taken at Original ground level to ensure depth
of C & G and further calculation of
embankment height as per Plan and profile
b) Second Step Plat Load Test on OGL: Before
starting the any dumping activity second plate
load Test (EV2) are conducted for verification
of the soil bearing capacity for earthwork.
i) Second Step Plat Load Test : It is required to be
conducted in-situ for measurement of strain
modulus EV2 of sub-soil ,compacted
emabankment fill ,prepared subgrade ,blanket
etc. at the frequency of 1 test per km of the
section as per clause 13.1(C) of guidelines and
specifications for design of formation for

DIRECT SHEAR TEST
0014.This practice in German railways and
recommended by UIC Code : 719 to measure
the quality of earthwork and blanketing after
compaction.
Second Step Plat load test is works on Following three concepts.
• Plate Loading Test : Test in which load is
applied in increments to a soil sample using a
circular loading plate and a loading device,
released in decrements ,and the entire process
is repeated .The average normal stress below
the plate is plotted against the settlements ,for
each load increment so as to obtain a load
settlement curve.
• Strain Modules: The strain modulus EV, is a
parameter expressing the deformation
characteristic of a soil and is calculated taking
values from the load settlement curve.
• Modules of Subgrade Reaction: The modulus
of subgrade reaction, KS is a parameter expressing
the elastic reaction of soil under a surface load. It is
determined on the basis of load settlement curve
obtained from the first loading cycle.

c) Compaction of Earth dumped- After getting the Approval from the Engineer, dumping is started from
borrow area. Compaction Procedure includes dumping, spreading of soil by means of motor grader,
sprinkling of water up to Optimum moisture content as derived in laboratory and compacted by mechanical
means as Roller. Good Supervision is required during the compaction for proper count of the No. of passes
required for compaction as per Trial patch data.

d) Field Density Testing of Compacted Layer: After the rolling operation is completed, the compacted layer shall be checked to measure the amount of compact ion achieved during construction. There are various methods are stated in the “GE -1 Guideline for the Earthwork in Railway Projects” namely,
• Sand Replacement Method
• Core Cutter Method
• Nuclear Density Gauge (May be Used as consultation with RDSO)
• Compacted Meter fitted on Roller (May be Used as consultation with RDSO)
Sand replacement method is commonly used to check the in-situ density of soil. However SRM method of testing is very time consuming, CTP 14 project is using Nuclear Moisture Density Gauge (NMDG) after getting approval from RDSO.
• Sand Replacement Method (SRM): The basic principal of sand replacement method is to measure the in-situ volume of hole form which the material was excavated from the weight of sand with known density filling in the hole. The in-situ density of material is given by the weight of the excavated material divided by the in-situ volume.
• Nuclear Moisture Density Gauge (NMDG): Nuclear moisture/density gauges are testing devices that use low level radiation to measure the wet density, dry density, and moisture content of soil and granular construction materials.
This work procedure has been adopted to determine the percentage of compaction and Moisture content of compacted layer as per ASTM D2922 AND ASTM D 6938-10.
This test is required to conduct in site for measuring degree of compaction and moisture content of compacted layers of embankment, prepared subgrade, Blanket layer etc. This test has been included as a future developments for quality assurance test on compacted surface.
The purpose behind using Nuclear Density Gauge can be attributed to the fact that it is a faster method than sand replacement method and can be used at sites where there is a huge quantity of earthwork involved.
This paper elucidates the use of NDG and the terminologies related to the same. Also, the working as well as procedure for operating the equipment
along with appropriate safety measures and
regulatory framework have been described in detail.
The sources which have been referred to have been
mentioned in the end.
The NMDG works on following concept.
The radioactive sources in NDG’s are always
emitting radiation. When the NDG is not making
readings, the source must always be retracted to the
“Safe” position, with the source secured inside the
tungsten shielding block.
Figure 9 : A diagrammatic representation of the major parts of an NDG
Wet density is measured using a Cesium 137 (Cs-137) gamma radiation source, a pea-sized pellet fixed in the bottom of the source rod, and two Geiger-Muller tube gamma detectors at the rear of the gauge. The Cesium gamma source is lowered to the desired test depth by releasing the handle. When the test is started, the detectors in the gauge record the count rate of the radiation transmitted directly through the soil layer, displaying wet density readings on the keypad. A more dense material absorbs more gamma radiation, resulting in a lower gamma count reading, which converts to a higher wet density value. The volume of material assessed include the material between the source and the detectors, but the actual volume is not precisely known (refer to Figure 10).
JUNE 2019DFCCIL JOURNALTh
e
78
In direct transmission mode the NDG determines an
average density from the source rod to the gauge, if
the NDG is not seated properly and an air gap exists
(which has a zero density) the average wet density is
reduced proportionally. If the gauge cannot be
seated on a flat surface, fines from the measurement
layer or dry sand passing 600 µm must be used to
provide a complete seal between the NDG base and
the surface being tested.
Moisture content is measured using an Americium-
241 /Beryllium (Am-241/Be) neutron radiation
source that releases high-energy neutrons. These
‘fast’ neutrons are slowed by interaction with the
hydrogen atoms. A ‘cloud’ of slow neutrons forms
around the gauge, passing through a Helium 3 tube
detector. This detects only the count rate of the ‘slow’
neutrons. The neutron source is fixed inside the
gauge base, with the detector beside. A wetter
material will slow a greater number of neutrons, and
also reduce the zone of influence into the material
(refer to Figure 4). Not all hydrogen atoms are in
water molecules, the mineralogy of the material
being testing may contain hydrogen. The moisture
content determined by the NDG can be used as a
guide but is not accurate and should never be used in
further calculations or reporting.
Radioactive sources decay over time, producing
lower raw count levels. The field counts must be
standardized by comparison with the ‘Standard
Count’, taken using a standard setup. All
calculations and processing of results uses the count
ratio, the field count divided by the standard count.
This applies to both density and moisture systems.
The radiation systems of the NDG provide indirect
measures of wet density and moisture content. The
systems (the count ratio response) are calibrated
against blocks of known wet density and moisture
content, prior to use of the NDG in the field. The
maximum calibration interval is two years.

• Filter criteria should be satisfied with subgrade
layer as given below.
Criteria – 1: D15 (Blanket) < D85 (Subgrade)
Criteria – 2: D15 (Blanket) > 4 to 5 X D15

Criteria – 3: D50 (Blanket) < 25 X D50
(Subgrade)
b) Frequency of Material Testing: One set of test for every 500 Cum.
c) Selection of Blanket Material: Proper survey of
area close to Embankment site, at different locations
needs to be carried out to identify suitable sources for
blanket material required. Aim of such source
identification survey is to be use naturally available
material, which is cheap and conform to the
specification laid down.
If naturally available material do not meet the
desired specification, blanket material can be
produced by mechanical process from crushing or
blending method or combination of these two
methods.
d) Mechanical produced Blanket Material: Course
and Fine aggregate produce in the crusher plan are
blended in the mechanical pugmill. The proportion
of the coarse and fine aggregate is established in the
laboratory. The pugmill shall be calibrated as per
proportion established in laboratory before starting
production from pugmill.

H) Challenge Facing:
a) Total scope of earthwork is 2.75 Crore cum.
Getting this much amount of suitable soil for the
embankment fill is a real challenge for the project as
the alignment is passing through National Capital
Region (Mewat, Dharuhera, Faridabad, Noida) and
industrial area of RIICO and Faridabad.
b) Moreover, farmers are taking crop for all four
seasons, local people are not ready to give their land
for the excavation of soil.
c) Due to opening of upcoming large infrastructure
projects in nearby vicinity of the alignment of CTP 14
particularly in Rewari, Sohna and Prithla area, land-
owners are not ready to lease the land to extract the
soil considering expected higher rate of the soil in
future , which creating problems in progress.
d) From DFC CH No. 131+000 to end the chainage of
this project, as our alignment is passing near to
NOIDA DEVELOPMENT AUTHORITY, we are
finding difficulties to excavate the soil within 15 km
of radius as most of the land comes in the Noida
Authority. So, we are going beyond that, which
increases the leads from alignment causes less
productivity.
I) Lesson of Learning:
We have huge amount of earthwork quantity in our
project. For the approval of compacted layers, we
initially opted the methods of sand replacement
method as mentioned in our GE-01 as per RDSO
guidelines which is time taking and tedious job. So,
we opted another method i.e. Nuclear Moisture
Density gauge which took very less time to check our
compacted soil beds. But for this, we waited almost 6
months for getting the approval from RDSO. That
causes lagginess in our project.
The purpose behind using Nuclear Density Gauge
can be attributed to the fact that it is a faster &
accurate method than sand replacement method and
can be used at sites where there is a huge quantity of
earthwork involved.
So, it should also be included in our RDSO guideline,
so that Future DFCC Projects don’t need any kind of
approval from RDSO and testing with NMDG can
start from the initiation of the project.

NETWORK STATEMENTSIN EUROPEAN RAIL TRANSPORT SECTOR – A GATEWAY TO TRACK ACCESS CHARGES
SYNOPSIS:Apart from being the first of its kind in India to construct fully dedicated track corridors for freight transport, DFCCIL also has the unique task as Infrastructure Manager (IM) to assess the charges to its tracks accessed by Railway Undertakings (RU). While Indian Railways will be the only RU in the present scenario of single operator regime, non-discriminatory access to all the Railway Undertakings will be the norm in a multi-operator regime of the future. Multi-operator regime already exists in European Union (EU) where RUs for both passenger and freight transport services enter into individual agreements/contracts with the IMs based on the guidelines issued by RailNet Europe (RNE).

RAILNET EUROPE NETWORK STATEMENT COMMON STRUCTURE IN EU
To establish a common ‘Europe-wide organisation’
for facilitating international traffic on the European
rail infrastructure across its Member states,
European Union (EU) has set up RailNet Europe
(RNE) in 2004. RNE’s mission is to help its members
meet the challenges of rapidly-changing railway
sector in Europe and to promote international rail
traffic by providing solutions that benefit all RNE
Members as well as their customers and business
partners. EU member states were able to separate the
provision of transport services and the management
of the infrastructure by the Single European Railway
Directive 2012. RNE also provides support as
regards compliance with the European Legislations
with harmonised international business processes,
templates, handbooks and guidelines.
What is a Network Statement?
Railway Directives of EU describe the obligation for
each Rail Infrastructure Manager to publish a
Network Statement which refers to various
documents that carry their own appeal procedures-
the Network Code, Engineering Access Statement
and Timetable Planning Rules. It is the key to market
access for the Applicants providing all the
information that they need to know in order to place
requests for infrastructure capacity, especially the
commercial, technical and legal access conditions. It
aims to provide Applicants who wish to operate
services on a given rail network with a single source
of up-to-date, relevant information on a fair and non-
discriminatory basis.
Article 27 of Directive 2012/34/EU mandates the following to all the stakeholders of Rail Transport sector of Member states:
1. The Infrastructure Manager (IM) shall, after consultation with the interested parties, develop and publish a Network Statement which shall be obtainable against payment of a fee which shall not exceed the cost of publication of that statement. The Network statement shall be published in at least two official languages of the EU. The content of the network statement shall be made available free of charge in electronic format on the web portal of the Infrastructure Manager and accessible through a common web portal.
2. The Network Statement shall set out the nature
of the infrastructure which is available to Railway Undertakings (RU), and contains information setting out the conditions for access to the relevant Railway Infrastructure as well as to Service facilities or supply of such Services connected to the network of the Infrastructure Manager, indicating a website where such information is made available free of charge in electronic format.
3. The Network Statement shall be kept up to date and amended as necessary.
4. The Network Statement shall be published no less than four months in advance of the deadline for requests for infrastructure capacity.
• RNE encourages its Members to adopt a Common Document Structure for their respective ‘Network Statements’ so as to provide standards of user-friendliness and customer orientation, and to assist those who need to consult more than one Statement for their intended operations across EU. Understanding Network Statements is essential for successful communication between IMs and Freight Corridors.

GLOSSARY
F e w o f t he EU M e m be r s ’ R a i l w a y Infrastructure Companies:
To understand the commonality and
adaptability to country specific market segments,
certain features (especially those related to Track
Access) can be seen from the Network Statements
of Germany’s DB Netz AG, UK’s Network Rail and
France’s SNCF Réseau along with the Network
Statement Template given by RNE:-
Network Rail Infrastructure Limited (Network
Rail) of UK owns, operates, maintains and develops
the main rail network in United Kingdom. This
includes the railway tracks, signalling and
electrification systems, bridges, tunnels, level
crossings and viaducts.
Operating Routes:
The day-to-day running of UK’s railway
infrastructure is carried out by the eight operating
routes and a ‘virtual’ route that is responsible for
freight and passenger operators who operate over
multiple routes. Each route operates as a separate
business unit, headed by a route Managing Director
and management team, which is responsible for
operations, maintenance, customer services and
JUNE 2019DFCCIL JOURNALTh
e
85
local asset management. Each route also has its own
accounting records to enable greater benchmarking
of financial performance and efficiency between
routes and to share best practice.
Two key elements of the national framework
are:
• A Technical Authority to set standards across
the network as a whole
• A System Operator to plan and allocate
capacity across the network as a whole
The routes are also supported by:
• Route Services Directorate
• Infrastructure Projects
• Digital Railway
Regulatory Authority:
Network Rail (NR) of UK is accountable to Office of
Rail and Road (ORR), the regulatory body, for
compliance with the obligations under their
Network Licence and Station Licence. These
authorise NR to operate the main rail network and
major stations (as listed in the Station Licence
schedule). Similar Regulatory body in France is
Authorite de Regulation des Activites Ferrovaires Et
Routiers (ARAFER) for SNCF Réseau and in
Germany, it is Federal Network Agency (FNA) for
DB Netz AG.
ORR is the railway industry’s economic and safety
regulator and is independent of government, but
accountable to Parliament. Any Railway
Undertaking (RU) wanting to operate trains on the
network must, among other things, have a ‘Track
Access Contract’ with NR which has been approved
by ORR. RUs may also be required to enter into
Station and Depot access agreements.
Disclaimer by NR: While primarily concerned
with information relating to the main rail network,
the objective of the Network Statement also extends
to the provision of further information regarding
railway facilities that link to NR’s network. The
extent of this information is subject to the level of
detail supplied to NR by the relevant facility owners
and operators when requested. In the cases where
NR is not responsible for the management of certain
service facilities, the related information contained
in this Network Statement is not binding.
Legal/Statutory Requirements:
The Network Statement of Germany’s DB Netz AG is
based in particular on the following legislation/
regulations (National and European):
• Railway Regulation Act (ERegG),
• General Railway Law (AEG),
• Implementing Regulations (EU)
• Railway Construction and Operation
Regulations (EBO),
• Railway Signalling Regulations (ESO),
• Railway Safety Ordinance (ESiV),
• Trans-European Railway Interoperability Law
(TEIV) and
• Technical Specifications for Interoperability
(TSI).
Liability insurance
Before starting services, the Applicant or involved
RU shall demonstrate to DB Netz AG that it has taken
out third-party insurance covering all claims that can
arise for whatever legal reason.
Information Technology Tools:
RailNetEurope (RNE) provides Infrastructure
Managers and Operators with various computer
tools in order to ease international train path
planning and control:
Technical Specifications for Interoperability
(TSIs) define the technical specifications required to
underpin those essential requirements and
harmonise the technical and operational
characteristics of the rail network:
• Control, Command and Signalling (CCS) TSI
relates to the train control and train protection
systems.
• Infrastructure ( INF) TSI def ines the
characteristics relating to gauge clearance,
including the clearance between trains and
platforms in stations, and of the distances
provided between adjacent tracks and technical
requirements for track components.
• Safety in Railway Tunnels (SRT) TSIs relate to
the safety characteristics of tunnels.
• Rolling Stock Noise (NOI) TSI
• Rolling Stock Freight Wagons (WAG) TSI
• Rolling Stock Locomotives and Passenger
Carriages (LOC & PAS) TSI
• Operations and Traffic Management (OPE) TSI
• Telematics Applications for Freight (TAF) TSI to

keep track of consignments and to determine
when deliveries to customers will be made. This
is achieved through messages passed between
IMs and RUs that convey the status of trains at
all stages from path request through to actual
train running.
Train Information System (TIS) is an easy-to-
use, web-based application which visualises the
trains from origin to destination and supports the
train management by delivering data concerning the
trains along RNE Corridors and RFCs.
Categorising the Services:
In accordance with the extant regulations and
template of RNE, SNCF Réseau of France offers
services to Applicants, which are broken down into
the following categories:
- Minimum services on main tracks
- Basic services provided on service facilities
- Other services grouping together the additional
services and ancillary services both on main
tracks and service facilities, as well as
miscellaneous services
A set of ‘minimum services on the main tracks’
offered to an Applicant is called Minimum Access
Package which comprises of:
(a) Handling of requests for infrastructure
capacity; and
(b) The right to utilise such capacity as is granted
and, in particular,
(c) Such railway infrastructure including track,
points and junctions as are necessary to utilise
that capacity;
(d) Electrical supply equipment for traction current,
where available and as is necessary to utilise that
capacity
(e) Train control, including signalling, train
regulation, dispatching and the communication
and provision of information on train
movements; and
(f) All other information as is necessary to
implement or to operate the service for which
capacity has been granted.
In relation to rail facilities that are not part of the
main rail network, the provision of the Minimum
Access Package is the responsibility of the relevant
Service provider whose contact details are available
on website for any RU to use in order to obtain key
information such as hours of operation, capacities
and capabilities.
Charging principles for Minimum Access Package (MAP):
The amount of the train-path charge reflects the
relevant mandatory services. The relevant train-path
charge for the minimum access package is calculated
using the train-path kilometres in the relevant
market segment multiplied by the relevant charge
for the minimum access package in this market
segment.

Principle Market segments in the rail freight sector
for Germany’s DB Netz AG, UK’s Network Rail and
France’s SNCF Réseau are:
• Franchised passenger services
• Open access passenger services
• Freight services
The charge for the minimum access package per
market segment comprises the direct costs of train
operation per market segment, and a surcharge to
cover the full costs (full-cost surcharge) according to
the relative viability of the relevant market segment
as well as possible additional elements. The
calculation of the charge is based in principle on the
contractually agreed train-path kilometres. The
charge for the minimum access package
accommodates the total fixed costs incurred as a
direct result of train operation.
Principles of calculating costs that incurred as
a direct result of train operation:
To calculate the costs incurred as a direct result of
train operation, there is an investigation into
whether a change in the volume of traffic results in a
change in the service to be rendered by DB Netz AG
and thus in the costs. Thereafter, an analysis is
carried out as to the extent to which changing the
service to be rendered by DB Netz AG causes a
change in the costs. It is possible to determine a
correlation between traffic volumes and costs
incurred by DB Netz AG for the following cost pools:
• Timetable cost pool
• Operation cost pool
• Track Maintenance cost pool
• Track Depreciation cost pool
ORR of UK periodically reviews the charging
arrangements every five years. It is responsible for
developing the charging framework and Network
Rail is responsible for calculating all existing track
access charges within this framework. Ultimately,
the level of track access charges is determined by
ORR. Access charges are set by ORR such that
Income from such charges together with surpluses
from other commercial activities and any public
funds shall at least balance with infrastructure
expenditure; and the basic cost of providing the
main rail network, after taking account of other
revenue sources, is met by fixed charges and
variable charges to the RUs.
Network Rail levies a range of track access
charges on franchised passenger, open access
passenger and freight RUs. These charges may
include:
• Variable Usage Charge
• Electrification Asset Usage Charge
• Traction Electricity Charge
• Coal Spillage Charge
• Freight Only Line Charge
• Freight Specific Charge
• Access Charge Supplements
• Capacity Charge
• Fixed Track Access Charge
• Additional Charges
The purpose of the Variable Usage Charge is to
recover operating, maintenance and renewal costs
that vary with traffic. It reflects the short run
marginal cost and does not reflect the cost of
providing or changing the capability or capacity of
the network. The Variable Usage Charge is paid by
RUs. It is largely based on a bottom-up analysis of
our incremental costs.
First, the total variable costs associated with all
traffic on the network are established. Then these
costs are distributed between individual vehicles
based on their relative propensity to cause damage to
the network. This propensity is established from an
analysis of the causes of wear and tear to the
network, and the relative characteristics of different
rolling stock types. The cost of track maintenance
and renewal varies with factors such as axle load,
speed, unsprung mass and yaw-stiffness. The higher
a vehicle’s axle load, speed, unsprung mass and
yaw-stiffness - the higher the consequent
infrastructure maintenance and renewal costs. As
such, the Variable Usage Charge reflects these
characteristics. Freight variable usage charges are
specified on a pound per thousand gross tonne mile
basis.
Variable usage charges vary depending on the
commodity type being transported as the operating
speed and operating weight of a freight vehicle can
vary materially depending on the commodity type
being transported. The variable usage charge is
indexed, annually, to the Retail Prices Index.
Network Rail furnishes an ‘estimate of the
charge’ for a new vehicle type, to any RU when it
provides the information such as:
JUNE 2019DFCCIL JOURNALTh
e
88
• Tare weight
• Number of axles
• Unsprung mass
• Yaw-stiffness
• Maximum or operating speed of the vehicle
• Ride Force Count
• Operating weight
Other charge components:
1. New service discount:
In order to promote the development of new railway
services, DB Netz AG grants all Applicants time
limited discount in the form of a percentage decrease
to the standard usage charge. It is granted for a
period of 12 months from the commencement of
operations.
2. The train-path charge includes a component
that accounts for noise-related effects of train
operation:
The noise-related effects are considered such that
loud freight trains must pay a surcharge on the train-
path price. A train is deemed to be loud where more
than 10 percent of it consists of loud wagons. A
wagon is deemed to be loud if it does not satisfy the
limits listed in the TSI related to noise.
Additional services and their charges:
• Stabling on railway lines not covered by an
allocated train path for more than 60 mns (Euro
3.80 for each 60 minutes or part thereof)
• Navigability assessment for oversized vehicles
(basic price amounts to Euro 215.00 plus the
cost-based charge amounts to Euro 80.00 for
each 60 minutes or part thereof)
• Proof of bridge compatibility (Basic price plus
expenditure related charges depending on the
level of examination)
• Additional equipment on railway lines (per
hour charges including water and power
charges)
• Charge for disclosure of framework agreements
(Euro 80.00 per hour or part thereof)
Ancillary services (mostly on fixed rate charges):
• GSM-R based communication for RUs
• Navigability study.
• Operating schedule study
• Dispatcher workstations in control centres
• Timetable studies
• Running time calculations
• Printed timetable books and speed restriction
lists
• Key Management Centre (KMC)
• Network Traffic-Regulation Control System for
the Customer
• Live Maps
• Data acquisition licence
• Statistical Analysis
• Train path diagrams
Track access to Service facilities:
In addition to the track access charges, the Access
and Management Regulations provide for
entitlements to track access to facilities and the
supply of services. Network Rail may recover the
costs associated with the following charges:
• Station Long Term Charge - to recover the
maintenance, renewal and repair (MRR)
expenditure associated with all the Stations,
levied on a constant annual basis.
• Depot Charges - in respect of the light
maintenance depots that Network Rail leases to
depot operators (who are either RUs or
specialist train maintenance companies).
• Qualifying Expenditure - recovers the operating
costs of common amenities at managed stations
such as station cleaning, refuse collection and
disposal, insurance, utilities, and the provision
of competent and suitably trained staff.
• Facility Charges - recover the costs of any station
enhancement funded by Network Rail at an
operator’s or user’s request. Incremental
ongoing costs resulting from the enhancement
(for example, for the operation, maintenance or
renewal of the asset during the recovery period)
may also be included in the Facility Charge.
• Property Rent- paid by Station operators under
the terms of their station lease. The rent provides
Network Rail, as the property owner, a share of
the income received by the Station operator
from commercial activities at the station- such as
retailing and advertising.
Performance enhancement system:
Article 34 of the Decree No. 2003-194 transposing
Article 35 of the Directive 2012/34/EU, lays out the
performance enhancement system as an incentive
JUNE 2019DFCCIL JOURNALTh
e
89
mechanism applying in a bilateral manner between
infrastructure manager (IM) and the railway
undertakings (RU). It aims at encouraging the both
to improve traffic punctuality in order to optimise
the operation of the network and improve the
quality of service offered to its users.
SNCF Réseau’s Reciprocal Incentives (IR)
system is to hold the stakeholders responsible and
thus optimise the capacities offered by the network
by creating systematic and fixed reciprocal
incentives involving penalising the infrastructure
manager (IM) or train path applicant in the event of
cancellations or modifications made by the latter.
On the one hand, it targets the effective and stable
issue of allocated train paths, by encouraging the
infrastructure manager of the national rail network
to not cancel or modify them, and on the other hand
it targets the early return and stabilisation of the
capacities reserved by train path applicants both for
freight and passenger transport.
The performance indicators of the railway
undertaking and of the infrastructure manager in
relation to each railway undertaking, expressed as a
ratio of "minutes lost/100 km", are calculated as
follows:
1. Proportion of minutes lost for which the RU is
responsible, over the number of train-
kilometres travelled by the RU;
2. Proportion of minutes lost for which the IM is
responsible, over the number of train-
kilometres travelled by the RU.
DB Netz AG’s Incentives and Penalty payments:
1. Compensation for additional train path costs
for work-related rail freight transport
diversions in the working timetable.
2. Automatic reduction- DB Netz AG reduces the
payable usage charge in the case of the
following faults which, due to a disruption,
have resulted in additional delay minutes:
Faults with the infrastructure, Faults with the
command and control system, Faults in
providing traction current, Staff-related faults
3. Charging arrangement for diversions due to
construction work after conclusion of the
Individual Usage Agreement (ENV).
4. Amendments and cancellation- After
conclusion of the contract, an amendment/
cancellation by the Applicant may only be made
before the scheduled departure with
appropriate charges.
Network Rail‘s performance scheme provides
compensation to RUs for unplanned delays and
cancellations which it is not directly responsible for.
It is a liquidated sums regime which provides
compensation based on the marginal effect on future
revenues of changes in performance caused by
Network Rail or other RUs. Track access Contract
sets out a framework by which compensation is paid
by either party if train or network performance fails
to meet set benchmarks. Bonuses are received if
either party delivers better performance than the
benchmark. The performance scheme therefore has
incentive properties for both parties (Network Rail
and RUs) to improve their performance.
Security:
A right of use of the Network Statement is granted
only after suitable and valuable security has been
provided. Security may be provided by customary
means of security, in particular an irrevocable,
indefinite, absolute guarantee of a credit institution
with a balance sheet total of at least 1 billion Euros
and with its registered office in the European Union.
The amount of security is determined on the basis of
the amount of expected charges for the train paths
allocated in the then current month and requested
for the next following month.
The Applicant can avoid the provision of security by
making an Advance payment which equals the
amount of services to be obtained from DB Netz
AG.\
Billing arrangements:
Each RU which operates on the main rail network
will for commercial issues communicate with an
assigned member of the relevant Network Rail route
team. The relevant Network Rail route team is
responsible for the cost recovery of monies owed to
Network Rail by the relevant RU, much of which is
outlined in the specific track access contract.
Remedies for non-payment include interest charges,
suspension of the contract and termination. All
invoices are sent to RUs via Network Rail Finance
Shared Services and are typically on a periodic (four
week) basis.

TECHNICAL PAPER FOR THE MODULAR CONSTRUCTION OF WELL STEINING AT YAMUNA RIVER (BRIDGE NO. 180) & AT HINDON RIVER (BRIDGE NO. 188)
SYNOPSIS:Over the past years, construction time & risk management in project’s execution is always associated with uncertainties because certain risk factors such as poor labor productivity, shortage of equipment, delay, cost overrun, time overrun are attributed to project delivery. It was also discovered that the external factors (technology, political and economic factor) are important in evaluating these constructs for further exploration of the construction companies to enhance risk management practice in all stages of the project activities. These risk factors have been generating many experimental interests among the construction stakeholders. These experiments aim at time reduction, better quality, ease of execution and handling, standardized safety, etc. This Project was designed with deep well foundations. The well sinking being one of the major critical activities took a huge amount of project completion period. Hence it was the need of the hour to experimenting and bringing the time cycle for the casting of well steining to as minimum as possible. The below methodology adopted for well steining casting ensured high standard safety and reduced time.

Challenges Encountered1. Stringent Time Deadline for Project completion2. Installation of air and water jetty arrangements
for catalyzing well-sinking activity3. Maintaining weight balance during concrete
pouring
Advantages1. Use of 2 cranes for sinking activity facilitated
well sinking leading to reduced time cycle for
continuous cycles of well steining casting and
sinking2. In Jack down Method, it takes time to remove
the beam assembly for steining shutter fixing
whereas in this method directly the shuttering
works of well steining were started.
Methodology1. Working Platform & Inner Shutter Fixing:
The working platform shall be installed inside
and outside area and position all vibrators and
needles at required locations. The Inner shutter
was fixed prior to reinforcement fixing,
followed by outer shutter fixing. A clear cover of
75mm was maintained from the outer most
reinforcement. After fixing of shutters, the
proper supporting arrangement as mentioned in
the approved drawings was done. The inner &
outer shutter were tied with steel prop in the
horizontal direction. The inner & outer shutter
joints were properly sealed with foam & putty.
Checking of the shutter for verticality was
approved by Engineer prior to the start of
concrete.
Fixing of inner shutter and rebar
2. Reinforcement Fixing:The bar bending schedule (BBS) was prepared as
per the latest approved drawing, submitted and
approved by the Client. Cutting and bending of
reinforcement steel bars mainly comprising
verticals, circulars and connecting links at the
yard was done. The cut & bent rebar were shifted
to the site for fixing. The rebar was fixed at the
site as per the spacing mentioned in the drawing.
The bars were being tied by 1.6mm binding wire.
Water jetting and air jetting arrangement were
provided to inner & outer faces for the sinking of
well till the top of steining

4. Concreting:M-35 grade concrete was prepared in the batching plant and shifted to the site by transit mixers. Concrete
was poured in layers of 300mm thick in clockwise & anticlockwise to avoid tilting of the well by using
concrete boom placer. The slump of concrete, temperature were checked at batching plant and site as
required.

5. De-shuttering:Remove the shutter after 24 hours of concreting. The maximum used horizontal steel props were loose
and removed. The outer & inner shutter each individual M.S. plate was removed. The forms were
conveniently removed without disturbing the concrete. Curing was done continuously and gauge
marking shall be done on four sides of the well.

Curing of well steining lift in progress
Measures adopted for Control of Tilt & Shift during SinkingFollowing precautions were considered to prevent shifting and tilting of well foundations:• The diameter of well curb was kept more than the external diameter of steining.• The well steining was symmetrically placed over the curb.• The outer surface of the well curb and steining were kept smooth.• All the sides were uniformly dredged.• The cutting edge was fabricated uniformly thick and sharp. • Proper markings and survey checks were done to regularly monitor the tilt and shift of the well
foundation
JUNE 2019DFCCIL JOURNALTh
e
96
Further, to rectify any shift or tilt the following provisions were adopted
Eccentric Loading
• The well tilt if any was rectified by placing eccentric loading on the higher side. Higher side is nothing but the opposite side of tilt or lower side.
• This eccentric load will increase downward pressure on higher side and correct the tilt.
• The amount of load and eccentricity was based on the depth of sinking.
• Greater is the depth of sinking of well, larger will be the eccentricity and load.
Markings on well foundation
Sample Report of regular monitoring of tilt and shift of well foundation

e
97
Excavation on Higher Side
• When well is tilted to one side, excavation was increased on the other side which is opposite to tilted side.
• This technique was used only in the initial stages of well sinking.
Water Jetting
• Provision for water jetting correction was kept in the design and execution of the well foundation.
• Water jetting on external surface of well on the higher side is another remedial measure for rectifying tilt.
• When water jet is forced towards surface of well, the friction between soil and well surface gets reduced and the higher side of well becomes lowered to make well vertical.

FAST TRACK CONSTRUCTION OF OPEN LINED DRAIN WITH GEOCELL ALONG WITH DFC FORMATION IN MADAR -IQBALGARH SECTION OF WDFC
1. SYNOPSIS:-Proper drainage arrangement along formation is necessity to ensure stable formation. Stone lined drain was being constructed for drainage arrangement in between the DEC formation and existing IR Track in Ajmer unit. The construction of stone lined drain was very slow due to availability of quarry/material, frequent change in mines and mineral policies and transportation. The stone lined drain is also not environment free, having frequent quality issue, require heavy repair and also not long lasting. To overcome these issues, now Geocell lined drain are being constructed in which helped in speedlly construction, long lasting, maintenance and environment free and cost saving. In large infrastructure project, construction of open line drain using Geo cell may be interest of All.
2. Introduction :-Ajmer Unit is executing DFC work from Madar to
Iqbalgarh section (342 Km) of the WDFC project.
Madar to Iqbalgarh have complicated section having
hilly terrain, high embankment etc. Maximum
alignment is almost parallel to the existing IR track
and construction of open lined drains are to be
provided for developing drainage arrangement in
between DFC & IR formation. These drains are
designed with such a material, shape and section
which provide adequate flow capacity, require less
maintenance and uniform longitudinal gradient
a d e q u a t e t o e n s u r e a s e l f - c l e a n s i n g
velocity etc. About 280 Km drains are to be
constructed between DFC & IR track in between
Madar to Iqbalgarh. WDFC project from Rewari to
Palanpur is targeted to commissioned by March-
2020.
As per Employer’s requirements, Stone Pitching
Drain are to be constructed having stone pitching of
230 mm with cement grouting on 100 mm thick
compacted moorum having trapezoidal shape.
3. Stone pitching drains and problem being faced:-Following type of the stone pitching drains are
being used:-
(I) Triangular (V-shaped) Drain where Toes of IR &
DFC overlaps.

Following difficulties are being faced during construction of stone pitching drains:-
1. Non-availability of stone/quarry due to
frequent banning on mining.
2. It is difficult to execute good quality of stone
pitching drain work as per drawing.
3. Construction as per approved drawings is
difficult to maintain and requires heavy repair.
4. Uniform longitudinal gradient in stone pitching
is not easy to maintain.
5. Difficult to ensure self-cleansing velocity in
stone pitching drain due to roughness.
6. Difficult in maintenance in future.
7. Progress of construction of drain with stone
masonry is very slow which causes delay and
affects the commissioning of project.
8. Construction of stone pitching drain is not
environment friendly.
9. Stone pitching drains are not aesthetic as
surface finishing is not good.
10. Stone pitching drains are costly in construction
and transportation of quarry/stone is difficult.
11. Removal of waste/excess material after
completion of work is difficult.
4. New technique and material for construction of open lined drain:-
Considering problems in stone pitching drain, it was
planned to use the modern technique and material
so that the problem being faced during construction
of drain using stone can be avoided.
5. Construction of Geocell open line drain:-
Sojiitz and L&T Consortium, is executing civil and
track work of CTP-1 & CTP-2 package for WDFC
which is from Rewari to Iqbalgarh. To overcome
these issues, contractor proposed to construct open
lined drain using Geocell as one of the main
constitute. Trial were done with open line drain
designed Geocell supplied by HM Geoweb system.
HM Geoweb Cellular confinement system provide a
wide variety of flexible stabilization for open
channels/drains and hydraulic structures. The
structural performance and durability of four
conventional protection materials such as concrete,
gravel, riprap and vegetation can be significantly
improved by confining the materials within the cells
of HM Geoweb systems.
The design of lined drain requires the maximum
anticipated flow conditions and the associated
hydraulic stresses for which the protection will be
depend. Subgrade drainage requirements and the
potential for long term or seasonal deformations of
the drain channel as a whole are also to consider. In
designing other factors as also include the surface
roughness on which hydraulic efficiency of the
drain/channel system and the ease with future
maintenance and sediment cleaning operations also
taken in account. The Geocell drains also have
compatibility with local environmental, ecological
and aesthetic requirements.
6. Geocell Drains:-
Thus, Geo Cell drains are being constructed with following drawing:-

joined/fastened using polymer ties before
start of concrete infilling.
5. Filling with Concrete: After geocell is placed
and fixed in position, the concrete infilling shall
commence from the top of the drain and
progress towards the bottom. It shall be ensured
that the height of the concrete infill drop into
geocell shall not exceed 0.5m. the concrete shall
overtop the geocell (10mm minimum) to trowel
smooth without the rim of geocell being visible.
6. Finishing operations: After concrete infilling to
the required geocell depth, the concrete
finishing operations followed by curing shall
commence along the drain.
7. V-Shape groove of 20 mm depth shall be
provided at every 2 m interval. Expansion
joint throughout the entire drain shall be
provided at every 20 m interval.
8. Specification and Properties of Geocell:-
Geocell works as a reinforcement to infill material i.e.
concrete and improve the strength and deformation
properties over the unreinforced concrete. Geocell
have three dimensional cell made of a strong and stiff
polymer which provide tensile strength and
increases the strength of the infill and the drain.
Geocell drain provide higher engineering
performance with sustained long life which is
achieved with much lower construction and
maintenance cost.
Geocell is cellular confinement system having
honeycomb geocell structure by 3D interaction of
concrete, cell walls. Geocell cellular confinement
system maintains the concrete compaction, thereby
increase the strength of the infill. Geocell works as
reinforcement mechanism which provide lateral and
vertical cellular confinement.

9. Benefits of Geocell Drains:-
1. Geocell drains are environment friendly. Geocell are three dimensional structure filled with concrete and
don’t require any intensive quarry, which also avoid transportation of stone/quarry material and also
lower carbon footprint.
2. Easy in construction with good quality.
3. Drain surface of concrete is smooth and maintain self cleansing velocity.
4. Geo Cell drain is maintenance free in comparison to stone drain. The cost of Project construction is also
minimised due to saving in maintenance and repair cost for long time.
5. Geocell drain are low in cost in comparison to stone drain and have high strength.
6. Geocell are perforated cellular and lined drain designed with Geocell are crack free and long lasting.
7. Geocell are designed to offer strength, flexibility and durability and cell fill with local available infill
material that are best suited. Geocell are made of polymer strip and have high resistance against
temperature and thermal cycling and have more durability.

1. Predictive Maintenance Trial: Track and Bridge
components at London Bridge are to be fitted with
Condition monitoring sensors during 2019 as part of
a trial to assess the potential for advanced
maintenance techniques to be deployed across the
UK Network. The trial is being led by Engineering
technology start up
"Enable My Team" working in partnership with the
University of the West England and Costain.
Maintenance staff will use augmented reality tools
via a smart phone or a head mounted display to
located failing components or structural faults and
read on screen instructions in real time to help
undertake repairs.
A network of sensors at the London Bridge test site
will gather data on tracks and station facilities such
as ventilation systems barriers or lighting. Condition
data will then be analysed using software called i-
RAMP or IoT enabled platform for rail asset
monitoring and predictive Maintenance. The
Objective is to predict when a fault is likely to occur
and highlight any stress points or component
failures on a 3D virtual model of the station and
track. Parameters to be monitored by the sensors will
include vibration, strain or pressure on a structure,
humidity and temperature. The London Bridge trial
is due to conclude in April 2020, after which more
extensive tests are planned with five more stations
being considered for fitment. A wider roll out of the
scheme is planned for 2011. (RGI Feb 19 pp 57)
2. China Network Expansion: On Jan 5 2019, China
launched the new time table adding 275 pairs of high
speed trains across the network. This takes the
national total to 2850 trains each way per day plus an
extra 220 which run at weekends. It is predicted that
a total of 2.99 billion journeys will be undertaken in
2019. In two weeks from December 25, Chinese
Railways put into service almost a dozen high speed
lines and Intercity railways along with a number of
mixed traffic and freight railways adding more than
3,000 Route kms taking the China's national network
to 130,000 route kms. (RGI Feb 19 pp50)
3. Automated Inspection on Network Rail:
Network Rail uses a fleet of 13 Inspection trains
across UK making the Network rail's asset
information service as the major business critical
resource underpinning maintenance and renewal
strategies. The trains are based at Derby. The
initiative began as a response to the Hatfield accident
in 2000, in which a Intercity derailed at speed by a
broken rail. The incident revealed Railtrack's lack of
knowledge about its infrastructure asset condition
and triggered extensive research into the
development and spread of rolling contact fatigue.
Within a couple of years Network rail had launched
the New Measurement train a 200kmph diesel HST
set specifically converted to monitor track geometry
on its principal routes. It also stepped up Ultra sonic
rail inspection by a factor of four. This has resulted in
reduction in Broken rails from 952 in 1999-2000 to
125 in 2011-12. Now it has plateaued to 100 per year.
Plain line Pattern recognition (PLPR) was
implemented from June 2013 to replace manual track
inspection. Enabling more effective more frequent
inspection to sub millimetre accuracy at line speed, a
technology that took more than two years to
develop. Seven cameras are mounted beneath the
IMT's Inspection car, looking down at the track from
different angles and illuminated by high powered
News and views from All over
JUNE 2019DFCCIL JOURNALTh
e
107
white lights. with a resolution of 0.7 mm, the
cameras can pick out track components including
individual ballast stones at up to 200 kmph. The
pattern recognition software identifies the rails,
sleepers, fastenings and joints as well as other track
components and stray debris. Advanced algorithms
analyse the images to assess the track condition
against standards and tolerances, looking for critical
faults and using red dots to highlight 'çandidate'
defects for manual interpretation.
A second inspection vehicle in the NMT carries the
track geometry measurement systems with 47 bogie
and body mounted sensors feeding data into a track
analysis programme that displays 13 major
channels, looking at ride comfort, dipped rails and
track twist amongst other factors. While it is possible
for the train to detect a serious 'block the line' faults,
which would be reported to the Signalling centre in
real time. A fraunhofer laser measurement system is
used to monitor the stagger and height of the
overhead contact wire on electrified routes in an
unloaded condition. Accurate to +/- 0.5 mm, this
can also measure wire wear by using spectral
analysis to calculate the distance between the
oxidation patches at each side of the flattened
contact area.
All the recorded data must be correlated by time and
location and this is done by using a real time
positioning system developed in collaboration with
several suppliers. Using tachometry and up to 15
GPS satellites simultaneously the location tool can
provide an almost military level degree of accuracy.
These vehicles also carry Ground penetrating radar
to assess the depth of track formation to a depth of
around 2 mtrs and KLD rail profile measurement
systems that identify rail wear and shape. The NR
likes to use the data to bring in change from 'find and
fit' to 'predict and prevent'.
NR is looking for other options like LIDAR which is
fitted to vehicles but not to the main inspecting
trains. NR is also looking for using drone to
undertake inspections without track access. Use is
also being made of the company's helicopter which
has high powered cameras that can look at the
condition of overhead line and line side fencing,
turnouts are fitted with inbuilt condition
monitoring system. (RGI Feb '19 pp:32). DFCCIL can
emulate the concepts elucidated in the original
article.
4. Reprofiling rails without facets: The concept of
tangential grinding has emerged in the past few
years as a new tool in the track measurements
armoury, aimed primarily at minimising the
development of rolling contact fatigue(RCF). The
article says wide spread use of hardened rails has
significantly reduced the wear rates and rail
replacement is triggered largely by RCF. Further
Turnouts where the transit of wheels from stock to
the switch rails, the closure rails and finally over the
crossing noses invariably produces higher dynamic
forces and lateral movements, magnifying the
process of defect formation. Conventional grinding
processes can leave distinctive ridges on the rail
surface known as 'facets'. These may linger on or
wear down quickly depends on the traffic
frequency and the quality of grinding. The facets act
as points of excessive contract stress between wheel
and rail. (RGI Feb '19 pp28).
5. Block to repair L-Canaresie subway line: despite
two years of preparation, New York Metropolitan
Transportation Authority announced that it had
dropped its plans for a 15 month blockade to repair
the line. Instead it accepted the recommendations
put forward by academics and engineers to limit the
anticipated disruption. ( RGI Feb '19 pp26).
6. Raising awareness about Climatic advantages of Freight Transport: A demonstration Freight train
has been making its way round Europe, raising
awareness of he role that rail freight can play in
combating climate change. Rail Freight Forward
(RFF) advocates that freight transport accounts to 6%
of the European GDP and demand is expected to
projected to grow around 30% over next two decades
which is equivalent of the total German Transport
sector today. Given that the Freight represents
almost third of the total transport emissions
equivalent to 275 million tonnes of CO2 per years,
RFF advises that without radical change the climate
impact can be expected to increase substantially in
future, ( RGI Feb '19 pp24).
7. Competitive Freight Wagon Concept: The CFW
concept is based on block trains comprised of multi
material lightweight wagons offering a significantly
lower tare weight and higher pay load than current
designs, with improved aerodynamics to lower
noise and energy consumption. Electro pneumatic
disc brakes would allow higher running speeds,
facilitating mixed traffic operation using available

Centre couplers will provide better longitudinal
train dynamics it is opined. Onboard power supplies
would support refrigerated goods and telematic
services for continuous monitoring of the wagons,
their loads and train integrity. (RGI Feb 19 pp20)
8. Battery Shunter: Colmar Technik supplied a
battery shunter in Italy. The 31 tonne vehicle can
haul upto 3200 T, has Zero emissions at the point of
use. The shunter has two 40KW traction motors and
is powered by three battery packs with capacity of
200AH providing 8 hours of operation. (RGI Feb '19
pp19)
9. Eliminating weeds by Concrete Canvas:
Concrete Canvas geosynthetic cementitious
composite material has been installed in Rotterdam
to prevent growth of weeds which could obstruct
the Optical character recognition systems used to
identify containers on passing freight trains. (RGI
Feb'19 pp19).
10. 3D Printed components: Three companies
have collaborated to use additive manufacturing to
produce four train interior components meeting the
standards required for use in UK rolling stock. The
components made are arm rest, a grab handle and a
seat back table. The aim is to produce replacements
for obsolete parts, enabling vehicles to remain in
service for longer. Operators will be able to produce
low-run parts as required, without needing the mass
production of large quantities. (RGI Feb '19 pp19).
11. Memorandums signed: India signed two
memorandums of understanding with Russia
covering educational development in Transport. It
also covers technical cooperation in specialist
railway disciplines. (RGI Dec '18 pp51).
12. Rail Drone specialist wings Innovation
challenge: Mandrid based railway surveying start
up won a regional innovation challenge for its work
supporting resignalling schemes in spain and
internationally (RGI Dec'18 pp51).
13. JR East on path of Change: JR East in their
vision document MOVE UP 2027, have noted that
the Business conditions are set to become far more
challenging over the next 30 years, largely due to the
changing Japanese demographic changes. There is a
strong possibility that demand will decrease. As well
as ageing population, changes in working patterns
resulting from spread of telecommuting and spread
of satellite offices, the ubiquity of Internet and
emergence of autonomous driving technology.
Hence JR East concluded that in the face of such
challenges it is difficult to envisage that growth will
continue on the basis of an unchanged business
model.
JR East in their vision document adopted in July 2018
believe that they should fundamentally shift focus
from railways to people. JRE wants to move beyond
providing services focussed on our railway
infrastructure to providing society with added value
that enriches people's lives. JRE will like to retain the
trust of the people for which Safety shall be their first
priority and the group will strive for 'extreme safety
levels' that will make this trust even more
unshakable. Their stations already serve as exchange
hubs for people, offering a multi layered network of
transport, life style and IT services, including the
Suica smrt ticketing and e-payment system. The
group must take maximum advantage of these
established strengths but the important point is not
to consider things exclusively from the perspective
of railway operations but to think carefully about the
enrichment means for customers and local
communities as well as employees and their
families.
JR East Vision document builds on three main
themes: making cities more comfortable, making
regional areas more affluent and developing
businesses for the world. ( RGI Dec 2018 pp34).
14. High speed freight service launched: FS group
freight subsidiary launched its first high speed
service designed to meet the needs of express
couriers, logistic operators, producers and
distributors. The Fast freight runs overnight at an
average speed of 180kmph with end to end journey
of 3 hrs 30 min.
